Public bug reported:
With kernel 2.6.32-21.32 I consistently get system freezes while
restoring data from a remote tape backup using amanda. The tape drive
is on a server, and I access it from the affected workstation using
amrecover.
The restore causes heavy network (max for 100Mbit network which is what
I have) and disk (which is a linux software RAID5 array on three SATA-II
hard drives connected to a Silicon Image fakeRAID controller (not using
the fakeRAID).
After about 30 minutes of this, the system reports different kernel
related crashes. CPU is not maxed on either CPU until the crash (i.e.
during the normal part of the restore the CPU is 30-40% on both CPU, but
when the system crashes one CPU is stuck at 100%)
Using the mainline kernel 2.6.34-0206034rc5 there is no problem.
Which kernel is the final Lucid release going to use?
Also I had no problems on Karmic Koala.
