Comment 43 for bug 585765

Unfortunately the many hard resets needed to reboot my multiple-linux AMD hardware (all 64 bits) (Ubuntu Lucid,gentoo, gentoo ~amd, Fedora 12, OpenSuse 11.2,Mandriva, Debian) resulted that my bios failed, and a check-up is now ongoing by a hardware specialist,;-))) So no detailed reports are available, only a couple of observations.

1) Linux versions with older kernels (pre 2.6.32) did not freeze like mandriva, OpenSuse, Fedora
2) Gentoo and Ubuntu had regular freeze of keyboard & mouse (both USB) and screen (2.6.32), 2.6.32/33/34 for Gentoo)
3) Observations made by databubble (item #39 of this thread) correspond to my experiences

However:
a) No special activity was required to get a freeze
b) Often freezing happened after some idle time (no human interaction with keyboard or mouse)
c) wireless (atheron ath5 driver) failed too. Pinging Ubuntu machine from my windows machine did not work after freezing
d) REISUB never worked (keyboard always dead) (e.g. caps lock also dead)
e) freezing occurs also when X was not running (!!!) (So no relation with Xorg and/or Nvidia ?)
f) After upgrading from Ubuntu 9.10, the freezing did not happen in the early days. Some indication when 2.6.32:22 was installed the problem were appearing, at least a high frequency seen after 2.6.32:22 and only rare before 2.6.32:22. A similar observation is valid (so far I remember) for the early versions of gentoo-2.6.32 kernels.
