As Peter mentions, I have had this bug with no X running, so it may well be kernel related, rather than xorg specific. I didn't get the freezes using the ubuntu upstream kernels .34 line, but I can't get ndiswrapper to work with that kernel, so I can't use it for extended periods.

Subject: [Bug 585765] Re: Ubuntu 10.04 random freezes

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.

Bug description:
Hello,

on my new laptop, a HP ProBook 6440b (with Core i5 and a plain Intel Chipset, 4GB RAM) I get randomly freezes of the whole system. I can't reproduce that, what means I don't know a aplication or usage of the system making it freeze. sometimes I have uptimes of a day, without freeze and sometimes it freezes right after booting the system.

I found out, that sometimes the MagicSysRQ (R-E-I-S-U-B) works and let me shut down the system, sometimes not. I don't know what makes that difference. In the system log I can't find any unusual entries. But I foun that the system log is still runing, so shuting down the wifi with the notebooks hardware switch for example is logged. Also the Wifi network connection to my router is not interrupted.
