------- Comment #8 from [EMAIL PROTECTED] 2007-03-13 03:46 PST -------
The TEXREL patch just appears broken. Not sure why WoW hits that path, but
you're actually not seeing a gpu lockup, just a segfault while holding the lock
(maybe it tries to start the wine debugger and keep the app running in the
meantime).
Here's a copypixrate backtrace (without HW locking in the span render
functions...). This is not driver specific.
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1214084896 (LWP 6058)]
0xb7951b5a in _generic_read_RGBA_span_BGRA8888_REV_SSE2 ()
at x86/read_rgba_span_x86.S:372
372 LOAD_MASK(movdqa,%xmm1,%xmm2)
Current language: auto; currently asm
(gdb) bt
#0 0xb7951b5a in _generic_read_RGBA_span_BGRA8888_REV_SSE2 ()

I'd need to take a closer look to figure out what's wrong (x86 asm is so
ugly...), it works if MESA_NO_ASM is set (MESA_NO_SSE does not help, it still
ends up in the same SSE2 path).
