Public bug reported:
I'm resubmitting #66500 because I no longer think it's an X.Org bug. It *looks*
like a kernel problem now because it affects too many things. The result is
that Edgy (beta and RC) is totally unusable on my machine, crashing/hanging
after a few minutes. Other than the crashes, symptoms include:
- Sometimes hangs for 1-2 minutes during boot without any activity
- Sometimes keys I press on the keyboard get repeated
- gnome-panel animations are *very* slow.
- Most GUI applications freeze when I click on a button
- Some applications (e.g. ssh server) tend to crash very often
- Ping reports "Warning: time of day goes back, taking countermeasures"
- Similar time problems reported by the window manager (don't have the log
anymore)
The above info makes it look like it could be related to gettimeofday() or
something like that. Some more observations:
- Disabling one of the CPU cores in the BIOS makes the random problems less
frequent, but they don't go away (machine still crashes)
- I tried both the i810 and the vesa drivers and there's no difference
So far, I tested the following distros:
Dapper i386: Runs OK
Edgy i386: Runs OK
Dapper amd64: Runs OK
Edgy beta amd64: BUGGY
Edgy RC amd64: BUGGY
Debian Etch testing AMD64: BUGGY
My setup is:
Dell Latitude D820 laptop
CPU: Core 2 Duo 2 GHz, 2 GB RAM
Intel embedded 950 graphics
No binary-only video card driver (or similar crap)
** Affects: Ubuntu
Importance: Undecided
Status: Unconfirmed
