--- Comment #7 from Rafael Wysocki
Interestingly enough, the hangs always happen when browsing the contents of a window using the mouse wheel.
This information was not correct. It also hangs during other kinds of activity causing the contents of a window to change quickly in response to either mouse or keyboard actions (like viewing a message in the message preview window in KMail or rewinding a Bugzilla page etc.). When it hangs I can log into the box over SSH and do 'echo t > /proc/sysrq-trigger'. Then, I always get the following trace for Xorg: Xorg S ffff880001014350 0 3068 3050 ffff8800794b9d48 0000000000000082 ffff8800794b9c98 ffffffff8024ff75 ffffffff80676000 ffffffff80676000 ffffffff80676000 ffffffff80676000 ffffffff80676000 ffffffff80676000 ffffffff80672de0 ffffffff80676000 Call Trace: [<ffffffff8024ff75>] ? unlock_hrtimer_base+0x13/0x15 [<ffffffff80243b22>] ? __mod_timer+0xb3/0xc5 [<ffffffff8044c065>] schedule_timeout+0x90/0xbf [<ffffffff802435d0>] ? process_timeout+0x0/0xb [<ffffffff80243a8b>] ? __mod_timer+0x1c/0xc5 [<ffffffffa0533eec>] i915_irq_wait+0x136/0x1d1 [i915] [<ffffffff8023320f>] ? default_wake_function+0x0/0xf [<ffffffffa0533db6>] ? i915_irq_wait+0x0/0x1d1 [i915] [<ffffffffa0503160>] drm_ioctl+0x1d6/0x26a [drm] [<ffffffff802b3f00>] vfs_ioctl+0x5e/0x77 [<ffffffff802b4299>] do_vfs_ioctl+0x380/0x3b8 [<ffffffff802b4328>] sys_ioctl+0x57/0x7a [<ffffffff8020bfbb>] system_call_fastpath+0x16/0x1b that seems to point towards the graphics driver. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
