I am seeing sporadic Xorg crashes with this patchset applied to a 7.0 stable series kernel, usually within a minute of logging into the desktop. The rest of system keeps running fine and there are no messsages in the kernel log. I am testing on an XP1000 with Radeon HD4350 graphics card. The same kernel without this patchset works fine -- no Xorg crashes. Indeed, it has been playing the dulcet tones of Pink Floyd through my sound system for the last hour without a problem. Example Xorg backtrace follows. In this case it is a fp exception but sometimes it is a segfault: [ 307.748] (EE) [ 307.748] (EE) Backtrace: [ 307.750] (EE) 0: /usr/lib/xorg/Xorg (xorg_backtrace+0x7c) [0x12022b3dc] [ 307.750] (EE) 1: /usr/lib/xorg/Xorg (0x120000000+0x230ae8) [0x120230ae8] [ 307.751] (EE) 2: /usr/lib/alpha-linux-gnu/libc.so.6.1 (0x20000720000+0x49e70) [0x20000769e70] [ 307.753] (EE) 3: /usr/lib/alpha-linux-gnu/libc.so.6.1 (0x20000720000+0x1a02e0) [0x200008c02e0] [ 307.753] (EE) 4: /usr/lib/alpha-linux-gnu/libpixman-1.so.0 (pixman_sample_ceil_y+0xbc) [0x200003472fc] [ 307.755] (EE) 5: /usr/lib/alpha-linux-gnu/libpixman-1.so.0 (pixman_rasterize_trapezoid+0xec) [0x20000347abc] [ 307.755] (EE) 6: /usr/lib/xorg/modules/libglamoregl.so (0x20003d30000+0x6c5bc) [0x20003d9c5bc] [ 307.755] (EE) 7: /usr/lib/xorg/Xorg (CompositeTrapezoids+0xb0) [0x12016a290] [ 307.756] (EE) 8: /usr/lib/xorg/Xorg (0x120000000+0x16fa04) [0x12016fa04] [ 307.758] (EE) 9: /usr/lib/xorg/Xorg (0x120000000+0x16a6c8) [0x12016a6c8] [ 307.758] (EE) 10: /usr/lib/xorg/Xorg (0x120000000+0x58578) [0x120058578] [ 307.758] (EE) 11: /usr/lib/xorg/Xorg (0x120000000+0x5d978) [0x12005d978] [ 307.760] (EE) 12: /usr/lib/xorg/Xorg (0x120000000+0x3f9b8) [0x12003f9b8] [ 307.762] (EE) 13: /usr/lib/alpha-linux-gnu/libc.so.6.1 (0x20000720000+0x2e490) [0x2000074e490] [ 307.763] (EE) 14: /usr/lib/alpha-linux-gnu/libc.so.6.1 (__libc_start_main+0xc4) [0x2000074e5d4] [ 307.763] (EE) 15: /usr/lib/xorg/Xorg (__start+0x38) [0x12003fa08] [ 307.763] (EE) [ 307.765] (EE) Floating point exception at address 0x200008c02e0 [ 307.765] (EE) Fatal server error: [ 307.765] (EE) Caught signal 8 (Floating point exception).
