Hi, I tried 4.2-rc7 and todays 4.2-rc7+git on a P4 PC with Intel 850 chipset and old Radeon graphics. The machine crashes during boot and starts spamming dmesg as fast as it scrolls. Netconsole caught the dmesg. 4.1.0 worked fine.

The first crash seems to be related to radeon_hotplug_work_func during radeon initialization.

Looks like a race at startup, I've sent a fix to dri-devel that should work.

Thank you - found it. Will test tomorrow.
