Hi Inuka, I've made some progress in getting more debug info. I loaded the -psb I posted last night - it still failed in the same spot, but I'd added some additional debug messages [1] to help narrow down where the crash is. Based on this info in the Xorg.0.log [2], I've determined that the failure is occurring during this call:
psbDRILock(pScrn, 0); # Implemented in psb_dri.c As well, thanks to having networking now, I've been able to log in remotely and run xinit in gdb, and now have a backtrace: #0 0xb7fa1410 in __kernel_vsyscall () #1 0xb7d8f4e2 in sigsuspend () from /lib/libc.so.6 #2 0x08049a97 in ?? () #3 0xbf981238 in ?? () #4 0x00001142 in ?? () #5 0xffffffff in ?? () #6 0xb7eab140 in ?? () from /lib/libc.so.6 #7 0x00000000 in ?? () Not very useful, but at least we finally _have_ a backtrace on it. I'm experimenting with a few other techniques to try getting a better backtrace (like against X itself). I'm also going to add more debug statements into the psbDRILock() routine to further narrow in on the crash from that direction.
