Bug#282798: kernel: Hang under disk load with Promise SATA controller
Package: kernel
With newer kernels, my system hangs as soon as "serious" disk activity
happens (like a "find /" or the daily backup script).
Problem does _not_ happen with 2.6.5, which ran stable uninterrupted
for 31 weeks.
Problem _does_ happen with kernel compiled from kernel-source
2.6.9-2.
The machine is an AMD64 Opteron machine, with Promise SATA controller
and RAID array of two disks. The kernels are 64bit kernels compiled in
a 64bit chroot.
It is a very hard hang: Magic SysRQ key is not responding any more.
Just before the hang, I get on the console, e.g.:
-------------------------- Begin console msg --------------------
ata1: command timeout
CPU0: Machine Check Exception 4 Bank 4b200000000070F0F
TSC 67743769F7
--------------------------- End console msg ---------------------
