https://bugs.freedesktop.org/show_bug.cgi?id=41668 --- Comment #18 from Przemyslaw Kochanski <przemyslaw@xxxxxxxxxxxxx> 2011-12-15 06:20:29 PST --- (In reply to comment #13) > Try the following options in the kernel command line in grub: > pci=nomsi > noapic > irqpoll > and see if any of them help. I've tried your suggestion and it worked! I've discovered the following: "pci=nomsi noapic irqpoll" no freeze "pci=nomsi irqpoll" no freeze "irqpoll" no freeze "pci=nomsi" no freeze "noapic" no freeze "" freeze So far without any of this options I can reproduce the crash in 100% cases under 1 minute of moving image in Gimp. I did it many times when backtracing. However, there is slight probability that I just got lucky with one of options. I'm 100% sure I've run `update-grub` after every /etc/default/grub change. Assuming that all of this options fix the problem, which option should I use (witch one disables least things)? I found the following but I don't understand much: noapic: [SMP,APIC] Tells the kernel to not make use of any IOAPICs that may be present in the system. irqpoll: [HW] When an interrupt is not handled search all handlersfor it. Also check all handlers each timerinterrupt. Intended to get systems with badly brokenfirmware running. pci=nomsi: [MSI] If the PCI_MSI kernel config parameter isenabled, this kernel boot option can be used todisable the use of MSI interrupts system-wide. And finally: Is it a proper fix, or just a workaround? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
