Public bug reported:
hi,
i'm not sure if i chose the right package, so please correct if
necessary!
the problem of system lockups with ubuntu related to amd cool'n'quiet enabled
has already been reported with earlier releases.
unfortunately, i can confirm lockups with gutsy tribe 5 (32bit) and todays
updates, which i could solve by deactivating amd cool'n'quiet in bios.
i've had the lockups with feisty (32bit) before, now switched to gutsy
testing.
the lockups occur unpredictably and mostly on an (almost) idle system, eg.
right after gutsy finished intall to hdd (still running off the live cd),
during gutsy package update, during light web browsing, after running amule for
a few minutes etc.
frequency of lockups ranges from within a few minutes to hours. after lockup,
my screen is unchanged with the exact content it had before, so no distorted
image whatsoever. mouse pointer and keyboard of course are frozen, too. hard
reboot is the only way to recover the system. the log files show no entries
that could be related to the time of the lockups.
the problem can be solved by deactivating amd cool'n'quit in bios. no
other workarounds tried yet.
the lockups do not occur with a well known commercial operating system,
where i tested with heavy system load under different software.
please let me know if i can assist with debugging!
cheers,
roots.
my system specs:
amd64 x2 4000+
asus m2n-e with nforce570 ultra
2gb patriot ddr2-800
ati radeon x1950xt
lg cdrw
