same problem here on a thinkpad T40, with kernel-2.6.27-0.354.rc7.git3.fc10.i686. Problem occurs when gdm starts, the driver is radeon. The BIOS default IRQ pin assignment with this laptop makes all interrupts shared on IRQ11. Created attachment 318107 [details]
dmesg log
dmesg until X starts. smolt uid for this laptop is pub_8be150b9-f49c-4c5e-968e-41db78fd37e4
This seems to be related to the PCMCIA yenta socket device. At least blacklisting it stops the interrupt from being shut off. Somehow related to this commit upstream?: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=de85422b94ddb23c021126815ea49414047c13dc;hp=2542335ccf34cfb442d3fd842d7e78ca5e649951 my case really occurs when X starts. After shuffling a bit the interrupt assignments in the BIOS (config/pci), I have a situation where IRQ 10 is concerned, with a smaller number of interrupt handlers, when X starts: [drm] writeback test succeeded in 2 usecs irq 10: nobody cared (try booting with the "irqpoll" option) Pid: 2660, comm: Xorg Not tainted 2.6.27-0.372.rc8.fc10.i686 #1 [<c046db32>] __report_bad_irq+0x33/0x74 [<c046dd42>] note_interrupt+0x1cf/0x221 [<c044b465>] ?

Associated kernel.org bug: http://bugzilla.kernel.org/show_bug.cgi?id=11700 This really does now appear to look like radeon. Closing, Dave has fixed this. New radeon drm kernel module in rawhide deals with IRQ properly now. |
Description of problem: interrupts stop working Version-Release number of selected component (if applicable): 2.6.27-0.347.rc7.git1.fc10.i686 but older versions recently have introduced this from 337+ How reproducible: 100% Steps to Reproduce: 1. Various actions may cause the kernel to lose interrupts, one such is running glxgears with radeon and observe the kernel disable interrupts all devices on IRQ 9 oddly. Actual results: System becomes unstable, network stops, ACPI switches to polling mode Expected results: No irqs are disabled.
