--- Comment #13 from Pierre Willenbrock <[EMAIL PROTECTED]> 2008-12-02 13:32:21 PST --- Created an attachment (id=20750) --> (http://bugs.freedesktop.org/attachment.cgi?id=20750) Small hack making the stuck irq go away It seems like i found a band aid for the stuck IRQ problem. If i put 100 into the for-loop, after some time the IRQ does get stuck, but with 1000 loops, i have not seen that again. I tested this loop at these other positions, and it always worked: * before the spin_unlock * after the posting read Making i915_enable_pipestat do nothing had a similar effect. I could reproduce the stuck IRQ using either APIC or XT-PIC(which annoyingly just hangs in an IRQ-loop forever), using a single CPU, and without any GL activity. My guess is this is a hardware timing problem, where the IRQ-state-machine gets into a bad state because two unknown events happen in too rapid succession. -- 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
