Gutsy was really stable, I never had a problem for the longest time. When I upgraded to Hardy, I started getting random lockups that require hardware reboot. The lockups happen completely at random, usually within an hour. It "seems" to come faster when using the network (either wired or wireless). The lockup is total, no mouse movement, no numlock change, even the (wired) network ligths don't respond after a lockup. This is the same as bug 204996, but that bug has been reported with a fix released and scheduled to be released with Intrepid, so I'm affraid it has been ignored since then. As far as I understand, the fix is in kernel 2.6.25 (I have not tested it myself) but no fix as been released for Hardy (none that work for me anyway). Since Hardy is supposed to be LTS, I believe a fix needs to be released for it specifically but the other bug seemed to have been ignored since it was set as "fix released" (therefore this, otherwise duplicate, bug).
My hardware is nearly the same as the original 204996 poster: Dell C400 1GHz, 512MB, Broadcom BCM4306 wifi mini-pci card (Dell wireless 1350).
PS: There are no other problems. No problems rebooting after a crash, no blinking screen, nothing happening before the freeeze, it just stops responding, it is completely dead to anything. I checked in the kernel log files and there was nothing at the time of the crash.
HELP!
