Comment 24 for bug 128207

Happened to me twice recently, both times while being away from the system.

I don't recall the first time precisely, but today the machine wasn't doing much of anything.
The only apps running were Firefox (some seemingly innocent pages), Thunderbird, two terminals, emacs, and maybe pidgin.

I had the system in 'lock screen'-mode (display turned off), with the 'Skyrocket'-screensaver running.
When I returned and turned the display back on, I was at the gdm login prompt. All my manual mounts were still mounted, so gdm had just cycled, I concluded.

Indeed, in syslog:
gdm[10640]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0

Ubuntu 8.04 Hardy Heron.

$> uname -a
Linux skyscraper 2.6.24-23-generic #1 SMP Mon Jan 26 01:04:16 UTC 2009 x86_64 GNU/Linux

$> lspci -vvnn

dmesg:
I'm not even thinking about attaching that, for it's entirely meaningless -- apart from the above gdm error.
Reason: it's flooded, every 2 seconds(!), with this message:
DoRxHighPower(): RF_ZEBRA, Upper Threshold: 99 LOWER Threshold: 70
That's a bug in its own right, one which apparently will not be fixed. Nice going.
