Hi, I've reported a few hangs/crashes since Jaunty alphas, but thought they had gone away, I hit another one last night and have some debug - it happened as I closed a tab in firefox (the button was still highlighted inwards) - the mouse cursor continued moving but nothing else worked (not even capslock) - it's not repeatable; my machine has an i945GM with an internal LCD and an external monitor. This was running a 2.6.28-12 #42 from Daniel Chen with a sound fix.
Gdb attach to the Xserver gives: (gdb) where #0 0x00007f8c92f27cd7 in ioctl () from /lib/libc.so.6 #1 0x00007f8c91545343 in drmIoctl () from /usr/lib/libdrm.so.2 #2 0x00007f8c91545646 in drmCommandNone () from /usr/lib/libdrm.so.2 #3 0x00007f8c910c2ba8 in I830BlockHandler (i=<value optimized out>, blockData=0x0, pTimeout=0x7fff9d34d978, pReadmask=0x7de e40) at ../../src/i830_driver.c:2751 #4 0x00000000005370f8 in AnimCurScreenBlockHandler (screenNum=0, blockData=0x0, pTimeout=0x7fff9d34d978, pReadmask=0x7dee40 ) at ../../render/animcur.c:222 #5 0x000000000050170e in compBlockHandler (i=0, blockData=0x0, pTimeout=0x7fff9d34d978, pReadmask=0x7dee40) at ../../composite/compinit.c:158 #6 0x0000000000451d20 in BlockHandler (pTimeout=0x7fff9d34d978, pReadmask=0x7dee40) at ../../dix/dixutils.c:384 #7 0x00000000004ef561 in WaitForSomething (pClientsReady=0x137d690) at ../../os/WaitFor.c:215 #8 0x000000000044e020 in Dispatch () at ../../dix/dispatch.c:367 #9 0x0000000000433d8d in main (argc=10, argv=0x7fff9d34db58, envp=<value optimized out>) at ../../dix/main.c:397 I killed off the Xserver and it didn't restart - the following was in the logs: [57243.381583] [drm:i915_getparam] *ERROR* Unknown parameter 6 [67624.392049] [drm:i915_wait_irq] *ERROR* EBUSY -- rec: 631301 emitted: 631302 [67627.404050] [drm:i915_wait_irq] *ERROR* EBUSY -- rec: 631301 emitted: 631303 [67629.108050] [drm:i915_gem_idle] *ERROR* hardware wedged [67642.010280] [drm:i915_setparam] *ERROR* unknown parameter 4 [67642.010309] [drm:i915_getparam] *ERROR* Unknown parameter 6 [67642.089084] [drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck [67643.138064] [drm:i915_getparam] *ERROR* Unknown parameter 6 Those unknown parameter 6's seem to happen pretty regularly but don't seem to cause any issues. Machine doesn't run compiz. (My earlier Jaunty issues were in #346910 - although I haven't had any crashes to blue like that recently).
