BUG: warning at kernel/softirq.c:141



Hello ext3-users,

we have an oopsy situation here:

we have 4 machines: 3 client nodes, 1 master: the master holds a fairly big repository of small files. The repo's current size is ~40GB with ~1.2 M files in ~100 directories. Now, we like to rsync changes from the master to the client nodes, which is working perfectly for 2 nodes, but our 3rd node oopses "sometimes", rendering the machine unusable and we are forced to reboot the box (no serial console, no sysrq possible). Below is the oops and a few details, more details, .config, dmesg, tune2fs-l are here:

http://nerdbynature.de/bits/2.6.18-debian

Yes, it's a debian kernel, 2.6.18-2-k7 to be specific, it happend with 2.6.17-2-k7 too. We haven't tried vanilla yet. All boxen are the same hardware (amd64, 32bit kernel+userland (debian/unstable) 1GB ram).
The filesystem is residing on a raid0-md, consisting of 2 sata-disks.

Any ideas what could cause this?

Thanks,
Christian.
