[Dri-devel] Finally looking at the DRI SMP issues

[Ian Romanick]

I finally have access to an x86 SMP box, and I have a few cycles to look 
at the SMP related problems.  I'm using an AGP G400 and quake3-smp. 
Like Dieter, I get a black screen and a hung program.  When I break in 
with GDB, here is the stack trace.  Dieter, does this match what you see?

0x00162c32 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
(gdb) bt
#0  0x00162c32 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1  0x0040d7bb in __lll_mutex_lock_wait () from /lib/tls/libpthread.so.0
#2  0x00006a49 in ?? ()
#3  0x003baa24 in ?? () from /usr/X11R6/lib/libX11.so.6
#4  0x0892d078 in ?? ()
#5  0x0040a976 in _L_mutex_lock_26 () from /lib/tls/libpthread.so.0

Previous frame identical to this frame (corrupt stack?)
This is on a Fedora Core 1 system with today's DRI / Mesa CVS.
