Has anybody else been seeing random crashes and lockups using (k)ubuntu Jaunty? I upgrade from Hardy to Intrepid to Jaunty within the last month. Intrepid had some nasty KDE problem for me, but Jaunty seems great, except that it seems really flaky...

Here are some of the things I've seen so far:
  • I've run into many hard lockups. (No X response, no ping reply, no response from Num/scroll lock keys). I've had this happen within minutes after booting. Seems to always happen when I am moving the mouse.
  • I've had a few times where X makes my LCD fade to white; which I've never seen on this laptop before. (I used to get this on my old DELL (r128 ).. but I haven't had this problem in years...). This is pretty much a hard-lockup too.
  • I've had a couple of weird X lockups where the mouse works, and I can connect via SSH but whatever I tried, I can't kill/stop the Xorg process. I think that Xorg uses very high CPU utilization during this time. The "reboot" command wouldn't cause the system to completely shutdown, I've had to hold down the power button...


I've found that booting to by old kernel (2.6.27-11-generic) seems much more stable, but also a bit slower.

I would gladly report a bug, but I really don't have any details to report. A generic crash with no log messages isn't really helpful. But even with the older kernel I've still run into some crashes. With seem to be X-related.

I've installed and enabled the watchdog service on my system (iTCO_wdt) but it doesn't actually reboot during a hard-lockup.

Any ideas or similar experiences?

Here is some info about my hardware. I'm running an IBM T42, 1.7Ghz with 1535MB of memory. My Video card is a Radeon 9600 M10.
