Package: linux-image-2.6.26-2-686-bigmem
Version: 2.6.26-21lenny4
I keep getting soft lockups; the symptoms appear to be that user
processes become deadlocked when they try to access the disk, but the
kernel doesn't notice that anything is wrong.
It appears that the lockups happen when:
(a) my software (mdadm) RAID mirror is resyncing or checking
(b) some other program does heavy disk IO
I'm currently trying to work around the problem by disabling the
system's backups (which are a prime trigger in category (b)) until the
post-crash mirror resync is complete, combined with setting the sysctl
dev.raid.speed_limit_max to 1000. Just disabling the backups wasn't
sufficient because, it seems, various recovery tasks in the most
recent crash are sufficient to trigger the bug.
I observe that the message from the md driver, and the presence of the
sysctls dev.raid.speed_limit_{min,max}, suggest that the md driver is
using a fundamentally incorrect algorithm which depends on guessing
the available IO bandwidth.
Actual hard data:
* chiark locked up at 0355 on the 2nd of May. It did so shortly after
the backups start. chiark's backups are done with LVM snapshots and
rsync. I don't any more have information about exactly at what
stage the backups were at.
* chiark locked up again at 0355 on Sunday morning the 6th of June.
In this case I was able to see that the system had successfully
created and mounted the LVM snapshot as the rsync process on the
backup master system was still present.
* Note that both these two crashes happened on the 1st Sunday of the
month. Investigating the kernel logs for the 2nd crash show this:
Jun 6 00:57:01 chiark kernel: [3250794.079478] md: data-check of RAID
array md127
Jun 6 00:57:01 chiark kernel: [3250794.079479] md: minimum _guaranteed_
speed: 1000 KB/sec/disk.
Jun 6 00:57:01 chiark kernel: [3250794.079479] md: using maximum available
idle IO bandwidth (but not more than 200000 KB/sec) for data-check.
Jun 6 00:57:01 chiark kernel: [3250794.079479] md: using 128k window, over
a total of 222297980 blocks.
However there is no sign of it completing.
* Shortly after I power cycled the system to get it back up, it locked
up again. At that point, the RAID was doing a post-crash resync,
and the crash happened at the point where the backup master
attempted to start on the next partition.
* Some research dug up some reports of first-Sunday-of-the-month
crashes associated with RAID integrity checks.[1] So I tried setting
the max IO bandwidth sysctl to the lowest reasonable value (by hand)
and left the system running. However, it locked up again as the
backups started.
* I power cycled the machine again and disabled the backups and made
sure they were truly stopped. However chiark locked up again mere
minutes after coming back up.
* I have now power cycled chiark once more and this time I set the
max IO bandwidth sysctl. So far it seems to have stayed up for
about half an hour.
If nothing more goes wrong I intend to leave the backups disabled
until the RAID finishes its resync, which we can expect to be some
time on Wednesday night.
chiark is running LVM-on-MD-on-LVM. So the two "disks" which form the
mirror which is resyncing are actually LVM LVs, and that mirror is
itself an LVM PV. The underlying hardware is a Dell R210 with two
WD SATA disks (WD7500AYPS-0).

seems relevant for example.
