It compiles and runs fine here, very snappy compared to the gentoo-sources I got used to :D , but for some reason I cannot find the place where I can choose the cpu-scheduler. I have seen it the first time I ran "make menuconfig" but now, whatever I try, It's not there anymore :?

That's because there is only one to choose from. SD 0.46

for all those having reiser4 probs, they seem to be gone with this patch mentioned here
use patch in addition to existing reiser4.patch

applied, compiled, works

you tried a stress-test? then you'll know that it will freak out under heavy load / strange situations ...

... so watch out when using this fs with 2.6.21 series !

- just have a data-back at your hand and you'll be fine :wink:

No problem, my last backup is only some days old. Since the beginning ob reiser4 probs i have it handy.
Instead of other persons that posted 'zero byte problems' - I got kernel ooops's while starting 'local' and/or a broken '/sbin/agetty'

Last weekend, after the last backup, I've tried/compared some fs's in a short.
I untarred my backup on differently formatted root-partition after another
-reiser4 with 'create=ccreg40,compress=gzip1'
-ext4 with extents
-reiser4

what should i say...
reiser4 with 'create=ccreg40,compress=gzip1' was fast unpacking my tar-backup and just the same speed compared to normal reiser4.
copying some mp3s on this partition was very sloooow - so i assume copying already compressed data to those disks is getting the speed increase backwards....not sure, I didn't get deeper into this.

reiser4 with 'create=ccreg40,compress=gzip1' on another partition that was used through dmcrypt/mapping partition was the killer- twice the kernel stalled and unacceptable speed 8O I believe s.o. would get better results with crypt+compress just out of reiser4...someday

ext4 with 'extents' was really 'moderate' in speed but useable as expected :lol:

At last i got back to normal reiser4 that beats ext4 in speed alot at least on a fresh formatted partition ;)
I will see that decission on fs's in a half year when reiser4 is becoming slow (again) ;)

Until now I haven't seen any 'freakout' with that new patch ontop of .21-viper1.
As my backup I have .20-viper4 kernel installed and my full sysbackup - so i'm quite save :)

At last there is real hope that namesys will get that patch problems away soon.

Doh! Just found out, that bdc (bitdefender-console) also wreaks havok [hope that is the right expression] with 2.6.20-viper4 reiser4 patch + 2.6.20-viper7 :D

will let the namesys people know, so that prog seems to trigger some not-yet discovered bug (also happens with 2.6.21-mm1)

Yes, it's good to see that expression's being used.

It gives me the creeps that an application can screw-up a file system: that's not right, Shirley?

Hizz all,

I've already posted my question to another post in the forum but I thought of posting it here as well since I am using viper-sources and my problem might be related with the kernel. Well here is the story:

I've formated my / & /home partitions using small gentoo r9 x86 live cd (contains 2.6.20-viper4 if I am not mistaken) and mount them with "-t ext4dev -o noatime,extents" . Then (as suggested in cheater's conrad-guide) and before writing anything to the disks I have run "e2fsck -Df" (I guess this one is to make the extents in the fs permanent (??) or not :D ). Anyway the problems starts whenever partitions are not cleanly umounted. The next time I boot I always get a kernel panic (kernel unable to sync). In such occasions I have to boot using the live cd and fsck the disk manually. To mention here that I am using 1.39-r1 e2fsprogs (which have the etx4 patches).

Does any has any idea what to look for?

Cheers!!

Yes, I just received a new AMD64 box, and I'm installing my first Gentoo ~amd64 system. As soon as I get my desktop up and running, I'll release -viper2. I believe that -viper2 will have better stability than -viper1.

Preemptible RCU has lost support from the -mm crew for breaking some drivers. The benefits were too small to outweigh the possibility of instability. The coretemp patches aren't in 2.6.21.

As far as I know, there is not a dynticks for x86_64.

What about updated ext4 driver?

Do you know something about the new adaptive readahead patch which should be much simpler and more efficient than the current one?

There is a preliminary patch, see http://www.gossamer-threads.com/lists/linux/kernel/765760
But I don't know how usable/stable it is...
