Hi!
I have two servers running reiser4 as root and data partitions.
Both are using 2.6.15.x kernels with reiser4-for-2.6.15-1.patch.
One is i386 UP with md over SATA, another is x86_64 SMP with i2o over
hardware raid.
I tried upgrading kernels on both servers to 2.6.16-cks9 (thats
basically 2.6.16.12 with some non-io related patches applied).
Both give me the same kind of error a few minutes after boot (during
intensive io):

After that happens, processes get stuck in D state, and only hard reboot helps.
Is there any patches that might help with this issue? Should I provide
any additional information to help with this bug?
Thanks.
