after updating to latest d-r-t, X crashes regularly, often just by starting firefox and waiting for it to restore all the previous open tabs. xorg-server 1.8.1.902 git libdrm/mesa/ddx kde 4.4.5 on rv790.

Did you update any other components as well (xserver, ddx, libpixman, etc.)?
yes. i updated git libdrm/mesa/ddx also. so I went back to an older rc3+ d-r-t kernel and ran it for 24 hours, no crashes. booted back to d-r-t git head and didn't start firefox this time, just started a nxclient session and within 10 seconds I get this X crash: Backtrace: [ 125.117] 0: /usr/bin/X (xorg_backtrace+0x28) [0x4a1358] [ 125.117] 1: /usr/bin/X (0x400000+0x636f9) [0x4636f9] [ 125.117] 2: /lib/libpthread.so.0 (0x7f365b498000+0xf120) [0x7f365b4a7120] [ 125.117] 3: /lib/libc.so.6 (memcpy+0x15b) [0x7f3659bc61fb] [ 125.117] 4: /usr/lib64/xorg/modules/libfb.so (fbBlt+0x100) [0x7f3657b2e3b0] [ 125.117] 5: /usr/lib64/xorg/modules/libfb.so (fbBltStip+0x40) [0x7f3657b2f0e0] [ 125.117] 6: /usr/lib64/xorg/modules/libfb.so (fbPutZImage+0x17e) [0x7f3657b3369e] [ 125.117] 7: /usr/lib64/xorg/modules/libexa.so (0x7f3657908000+0x11a3e) [0x7f3657919a3e] [ 125.117] 8: /usr/lib64/xorg/modules/libexa.so (0x7f3657908000+0x7fb7) [0x7f365790ffb7] [ 125.117] 9: /usr/bin/X (0x400000+0xd704c) [0x4d704c] [ 125.117] 10: /usr/bin/X (0x400000+0xb50fd) [0x4b50fd] [ 125.117] 11: /usr/bin/X (0x400000+0xb6055) [0x4b6055] [ 125.117] 12: /usr/bin/X (0x400000+0x2f5ec) [0x42f5ec] [ 125.117] 13: /usr/bin/X (0x400000+0x24de5) [0x424de5] [ 125.117] 14: /lib/libc.so.6 (__libc_start_main+0xfd) [0x7f3659b63bbd] [ 125.117] 15: /usr/bin/X (0x400000+0x24999) [0x424999] [ 125.117] Bus error at address 0x7f3652217000 [ 125.118] Fatal server error: [ 125.118] Caught signal 7 (Bus error).
