Bug#517449: Found in Debian 5.0.3 - Linux version 2.6.26-2-amd64 (Debian 2.6.26-19)
Sorry but after running for weeks with no problems using this kernel:
Linux version 2.6.26-2-amd64 (Debian 2.6.26-17lenny1) (dannf@debian.org) (gcc version 4.1.3 20080704 (prerelease)
(Debian 4.1.2-25)) #1 SMP Sun Jul 26 20:35:48 UTC 2009
On a Quad-Core AMD Opteron(tm) Processor 2372 HE stepping 02
I safe-upgrade'd on Friday to:
Linux version 2.6.26-2-amd64 (Debian 2.6.26-19) (dannf@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian
4.1.2-25)) #1 SMP Wed Aug 19 22:33:18 UTC 20

On Saturday this happened...

And by Monday the console was unresponsive, even to magic - sysrq. I am pretty sure the machine was not under any
stress at 9:30 on Saturday. No users, and backups start after 11pm.
Is it possible the some fixes have dropped out of current releases?
I have reverted the kernel back to Linux version 2.6.26-2-amd64 (Debian 2.6.26-17lenny1)

PS: For others who may pick this up in a search...to revert back try:
cd /var/cache/apt/archives
dpkg -i linux-image-2.6.26-2-amd64_2.6.26-17lenny1_amd64.deb
reboot
