Description:
I thought I would give hotplugging a try (since upstream is shifting towards there), but I have ran into various problems, which do NOT occur with hotplugging turned off:
- sometimes, 15-20 seconds after X startup the whole machine freezes - screen halts, mouse and gkrellm krells stop moving, no reaction from keyboard, music cuts out
- randomly the xserver "just dies" - it's usually after I press some keys (last time it was Alt+2)

Additional info:
xf86-video-ati: 6.10.0-1 (Ati Mobility Radeon X1400)
xf86-input-evdev: 2.1.2-1
xorg-server: 1.5.3-4
hal: 0.5.11-7

- xorg.conf is not present
- logs don't show much: http://rafb.net/p/ziRO4Q87.html


Steps to reproduce:
1) set up your system to hotplugging
2) start xorg, work normally
3) it dies!
This task depends upon

Please paste the log somewhere else too. rafb.net pastes last only 2 hours.

I meant 24 hours.

Right, after further testing, when the machine freezes, i am still able to ssh in from another machine and restart the Xorg - works ok.

Right, I think I have tracked down the problem. The ati R300 driver doesn't support XAA architecture, which xorg defaults to when using hotplugging. After setting the card to EXA mode in xorg.conf, the machine is much more stable. Anyone know whether this is worth sending upstream?
