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.
