Summary: Recent GEM kernels eventually start dropping interrupts on intel Product: DRI Version: XOrg CVS Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: General AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: [EMAIL PROTECTED] After a few minutes in Xorg on Eric's for-airlied branch, the kernel produces the following, irq 16: nobody cared (try booting with the "irqpoll" option) Pid: 0, comm: swapper Not tainted 2.6.27.5-100.fc10.x86_64 #1 Call Trace: <IRQ> [<ffffffff810832a7>] __report_bad_irq+0x38/0x7c [<ffffffff810834f3>] note_interrupt+0x208/0x26d [<ffffffff81083c20>] handle_fasteoi_irq+0xbb/0xeb [<ffffffff8101309e>] do_IRQ+0xf7/0x169 [<ffffffff81010933>] ret_from_intr+0x0/0x2e <EOI> [<ffffffff81332650>] ? _spin_unlock_irqrestore+0x33/0x3e [<ffffffff8105d675>] ? tick_broadcast_oneshot_control+0xf4/0xfd [<ffffffff8105cf53>] ? tick_notify+0x22a/0x37b [<ffffffff813354e6>] ? notifier_call_chain+0x33/0x5b [<ffffffff81058bb0>] ? raw_notifier_call_chain+0xf/0x11 [<ffffffff8105c95d>] ? clockevents_notify+0x2b/0x63 [<ffffffff811bc4e2>] ? acpi_state_timer_broadcast+0x41/0x43 [<ffffffff811bcd1c>] ? acpi_idle_enter_simple+0x197/0x1b4 [<ffffffff81286103>] ? cpuidle_idle_call+0x95/0xc9 [<ffffffff8100f279>] ? cpu_idle+0xb2/0x10b [<ffffffff8131f3dd>] ? rest_init+0x61/0x63 handlers: [<ffffffffa03d73d3>] (i915_driver_irq_handler+0x0/0x19d [i915]) Disabling IRQ #16 After this Xorg performance degrades significantly, in my case requiring mouse movement to force redraws. In other cases, this results in far more severe effects (e.g. file system corruption) -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
