[Hardy alpha 6] random system freezes on mobile sempron (amd64)

[Artyom Pervukhin]

Random system freezes, only hard reset helps.
System is Hardy alpha 6, dist-upgraded from Gutsy (which never freezed). Pattern undetectable - could freeze in 5 minutes after boot or after 12 hours. System can be highly loaded, or almost idle - all the same. Tried to boot with "noapic" kernel option, but that didn't help. Tried to use open NV driver instead of closed nvidia - results are the same.

Result of the following commands attached:
uname -a
cat /proc/version_signature
dmesg
lspci -vvnn

Seems to be duplicate of bug #182760
