Hi,

I found a machine to test my radeon patch on, but the system appears
to hang on entering kdb, even without KMS enabled:

[r...@f12 ~]# echo 9 > /proc/sys/kernel/printk
[r...@f12 ~]# echo g > /proc/sysrq-trigger
SysRq : DEBUG

Entering kdb (current=0xf34dd640, pid 1427) on processor 0 due to Keyboard Entry
[0]kdb> 

At this point the system appears hung -- my serial port and keyboard
input are totally ignored, and I have to power-cycle the machine.
Any ideas on how to debug this?

The machine's a Dell PowerEdge SC440, Celeron 430 CPU, 32-bit kernel
and userspace, running the current kgdb-next branch.  I booted with
"kgdboc=kbd nomodeset".  Here's a dmesg and lspci:

Thanks,
