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: http://dev.laptop.org/~cjb/kdb-hang-dmesg http://dev.laptop.org/~cjb/kdb-hang-lspci Thanks, - Chris. -- Chris Ball <[email protected]> One Laptop Per Child ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
