 Posted: Tue Sep 21, 2010 11:54 pm Post subject: experience with Kernel 2.6.34-r6 - kernel is unstable |
 |
|
I test since two weeks the gentoo-sources-2.6.34-r6 and run in many problems on three different hardware plattforms:
Lenovo T61 Notebook installed as 32 Bit Gentoo system
Intel Board with Intel(R) Core(TM)2 Quad CPU
Gigabyte Board with x86_64 Intel(R) Core(TM) i5 CPU
The first Problem show up on booting/shutdown with lvm2 on all three systems:
| Code: | | Internal error: Maps lock 13733888 < unlock 13737984 |
for every logical volume. On my T61 the Filesystem stops very often suddenly and the xfs filesystem unmount randomly partitions with high io traffic. This behavior decrease after switching from hbci to compatible sata mode in the T61 Bios. When I execute a lvm2 command like:
| Code: | ~ # lvcreate -n bla -L 64MB vgibm
Internal error: Maps lock 13733888 < unlock 13737984
Logical volume "bla" created |
I got the same Error.
A few minutes ago I got the first chrash on my 32Bit Core(TM)2 Quad CPU host while I execute an emerge --sync:
| Code: | fs_buf_get: failed to map pages

Now I have two non killable zombi processes an an unmount able /usr/portage partition. I had the same chrash on my T61 Laptop one week ago. The same problem on different host could not be an hardware problem.
An other problem occure since I switching to 2.6.34-r6 on my laptop T61 is permanently segfaulting of the X server when my Wacom tablet is plugged in:

Recompiling of the Xorg server with --emptytree did not change segfaulting. I reinstalled the kernel multiple times and compile him with the default values, the only change is the switch to the uvesa (as described in gentoo handbook)driver and enabling ksm (not on my T61 - I use KVM , sometimes on my Laptop without ksm)
Three systems based on different hardware shows the same behavior since kernel switching to 2.6.34-r6. My opinion is, this kernel is unstable and should not used on productive systems with LVM2.
My solution for this buggy kernel: | Code: |
echo ">=sys-kernel/gentoo-sources-2.6.34" > /etc/portage/package.mask |

Have you tried -r7? I'm currently using -r7 on a production system:
| Code: | | Linux cheddarsharp 2.6.34-gentoo-r7 #1 SMP Mon Aug 30 14:34:13 CDT 2010 x86_64 Intel(R) Xeon(R) CPU X3210 @ 2.13GHz GenuineIntel GNU/Linux |
With LVM2 volumes and haven't seen this behavior. I do not, however, run any form of X or window manager on the system. Perhaps the issue is a result of a misconfigured kernel? Something missing in the configuration? I'm not sure, but if you've tested it on 3 systems then that would at least rule out a hardware issue. |

It appears you have encountered a bug in XFS. Does the problem still occur in v2.6.35? There are no more v2.6.34 kernel releases planned, barring serious regressions.

Why do you blame LVM for this? The LVM error message is probably fall out from the guard page change. The BUG is an XFS failure to handle a NULL pointer.

You are free to do this, but I suggest you reconsider. You have already rejected a kernel with a fix for at least one root privilege exploit, and that mask ensures that you will never upgrade to newer kernel versions. |

I agree that somethings up with that kernel.
I upgraded 3 machines to it, and while all are working fine now, on my firewall box, I had to reconfigure the kernel to re-enable the iptables modules.
I did a make oldconfig when I upgraded (from 2.6.34-r1) to r6, and diff shows no difference between the .config files.
But when I booted from the new kernel, iptables failed to start (error on commit in iptables-restore)
The old kernel is fine
Eventually, I found I had to re-enable my iptables modules using menuconfig. That was weird |

I don´t want to blame lvm, because I use it since 1999 (not on Linux, but on HPUX 10.20, since 2002 on Linux) and it is a great block layer under the filesystems. I like it to use lvm`s as virtual disk for kvm systems (so much faster than vmdk`s under vmware). I only want to point the view on the heavy bugs on 2.6.34. I use Gentoo Linux since 5 years (xfs filesystem since 2003) and I cant remember to step in so much pitfalls and file system problems after the kernel switch to 2.6.34. XFS is a very old and sure file system - if anything is wrong on the block device, xfs unmount the device. I had one year ago heat problems with a hardisk and could recover after cooling down most of the data.
I switched back to 2.6.33 and will have a look on my system the next week. If 2.6.35 go stable I will switch again an test (after a full backup  ) May be the X Server segfaults could exist about problems with the wacom driver or udev. I remember an update in the last weeks. The last booting in 2.6.34 in the morning I detect a strange behavior again - kdm don`t want to start and hung while starting the X server that chrash with a segfault. I replay this scenario 4 times, then I put the mouse out of the graphic tablet. After that xdm and X start normal - I put the mouse back to my wacom tablet and could use the mouse normally. Under 2.6.33 start everything normal - but I have a look on it.
I don´t want to blame anything on this great distribution, I only a little bit nerved about the filesystem problems, because I am frightened about my data. |
