Hi, I have successfully compiled and booted the
current love-sources. They are working great so
far, but I have encountered a big problem: I can
neither mount cds nor dvds. My system is keeping
me telling this:
Code:
unable to mount: wrong filesystem type, illegal op-
tions, superblock of /dev/cdroms/cdrom0 damaged
or too many filesystems mounted


though i was not sure what had caused it, i have
the same problem.

also, i get the following error message when i try
to mount an iso using the loopback device:

ioctl: LOOP_SET_FD: Invalid argument

The loop problem has been encountered by lots of people. AFAIK it's due to some of the patches in 2.6.1-mm1/2, the next release may fix things if it's based on -mm3.

@mondauge

Looks like you are trying to mount the dvd via SCSI.....have you compiled that in? You might want to try mounting via
Code:


mount /dev/hdc /mnt/dvd

or whatever....

I too have the 'unable to identify cd-rom format' error when trying to mount cds.... audio cds work fine, I guess because they're not mounted. Don't use the cd very much, so don't really know when this started... hope mm3 will fix this, like Wedge said

sawanv: No, I use ATAPI with my DVD and CD-Recorder. Nevertheless, I have SCSI support compiled in, because I need it for my USB stick (which hoepfully works, when I get it back :-) )

Would it be worth making a version of love-sources without the mm patches? A few versions ago, mm broke reiser4 for me. Now people are having CD trouble. I'm sure there have been many other mm-related problems. I'm back to using my custom-patched 2.6.1 because of lockups. I can't be sure they're love-related, but I'm not taking any chances. Now I have all the best (IMO) features of love-sources (cfq, runtime-selectable IO scheduler, UDF packet writing, reiser4, and VM swappiness), without the instability of mm. Am I the only one who would like an mm-free version of love-sources?

mm-sources form a key part of love-sources. they get released fairly frequently, and any problems in them are sorted by the next release. It doesnt cause many problems having to hang back a love release for a week or two

I don't know about mainline, but 2.6.1-mm3 still has loop problems for me. The wierd thing was, some of my loop devices worked, and others did not. For example, my encrypted swap (which is cryptoloop of a whole partition) worked fine.

I have my /home partition split (using software raid 0) across several volumes which are stored on an MSDOS fs. This allows me to mount the same partition in VMWare/Windows and native linux, without using sketchy raw partition access (I can use hgfs instead under VMWare). Well, these don't work, losetup gets a bad seek error if I run it under strace.

I have my encrypted partition split up in precisely the same way, into MSDOS files. The only difference (except the nubmer of files and their sizes) is that I use cryptoloop for these. Amazingly, these work fine!!!

I can't figure it out. The only thing I can guess is that there is some kind of error which crops up trying to loop devices of particular sizes, like maybe if the device size is modulo the block size it works or something...

Here are the sizes:

Code:
bad-penguin greg # blockdev --getsize /dev/scsi/host0/bus0/target0/lun0/part7
8000307
bad-penguin greg # ls -l /mnt/node/HOME.bin0 /mnt/node2/e0.dat
-rwxr--r--    1 root     root     2000000000 Dec 31 03:08 /mnt/node/HOME.bin0
-rwxr--r--    1 root     root     1697177600 Jan  3 21:07 /mnt/node2/e0.dat


yucky. loop always seems to have problems, I am slowly learning to hate it. :evil:

Hi, I have got a very strange problem:
I was playing around with 2.6.1-love2, 2.6.1-love3 and the gentoo-dev-sources 2.6.1, in order to find the best kernel for me.
(By the way: I had the CD/DVD mounting problem in 2.6.1-love3, too, so I reverted to the gentoo-dev-sources)
The result of playing around carelessly was getting my nvidia-kernel dependent of love3 and I can't get rid of it!

Take a look please:
Code:
# emerge -ep nvidia-kernel
 
These are the packages that I would merge, in order:
(...)
[ebuild  N    ] sys-kernel/love-sources-2.6.1-r3
[ebuild  N    ] media-video/nvidia-kernel-1.0.4496-r3


When I put a "#" before PORTDIR_OVERLAY in my /etc/make.conf, I get the following:

Code:
# emerge -ep nvidia-kernel
 
These are the packages that I would merge, in order:
 
Calculating dependencies \
emerge: there are no masked or unmasked ebuilds to satisfy "virtual/linux-sources".
 
!!! Error calculating dependencies. Please correct.


I have already tried to "emerge sync" (with #PORTDIR_OVERLAY), because I thought it would rebuild the dependency tree, but the problem persists.

As you might guess, I don't want to keep 2.6.1-love3 'til the end of all days just for the sake of nvidia-kernel. :?
Please help me out. :)

Nngh, tough decision here. I like playing with love3, but I also purchased Win4Lin so I could play with it...is there any possibility at all that someone could come up with a modified love3 that will patch against lin4win cleanly?

supernova: open /var/cache/edb/virtuals and look for a line that says something like "virtual/linux-sources sys-kernel/love-sources". Delete that line and see if it helps. It'll probably still want you to install some set of kernel sources though, because nvidia-kernel needs to be built against them. Once you emerge a different set things should be OK again.

the cd/cd-rw/dvd mounting doesn`t work for me either

the log says: unable to indentify cd format

mount says: wrong fs type, bad option, bad superblock on /dev/dvd, or too many mounted file systems

what am i suppose to do ?

downgrade to 2.6.1-love2, which works fine at the moment, and wait until -love4 or 2.6.2-love1 comes out

I don't think -love4 is too far away, but it'll depend on when steel300 can get time to work on it.

Yes, but the new release that fixes the old bugs introduces new bugs. That's why love-sources never seem to work for everyone (beyond user error). Ideally we'd all be helping fix the problems caused by experimental mm patches, while enjoying the added features of love-sources. Some of us, however, would rather have a stable release with the nice extras of love-sources. That's what I prefer, at least.

I must admit love-sources has been a great source of inspiration, and the love-sources threads are good for finding solutions to my compile problems because the maintainer(s) must have fixed at least all of my problems or else love-sources wouldn't compile. The problem is the mm patches don't seem to help performance and only make my system unstable.

You seem to have the perfect solution, which is the same thing I do- just pull what patches you like/use and work for you, and leave out everything else.

It's good to know I'm not the only one. Even if you don't use everything in love-sources, it seems like the only thing that hurts stability is the mm patchset, so none of the other stuff would cause problems. Don't like reiser4? Don't compile/use it. CFQ giving you trouble? Don't use it. UDF packet writing causing oopses? Again, just don't compile/use it. Bootsplash casuing problems? You see the pattern. Probably the only thing you're "stuck with" is vm swappiness.

Actually, you can just patch -R the swappiness patch and then you're good to go.

i'd like to know where to get the vm swappiness/
nicks' scheduler patches so that i may add them to
the kernel sources i use myself.
