I just got this OOPS:
irq 9: nobody cared (try booting with the "irqpoll" option) Pid: 0, comm: swapper Tainted: P 2.6.26.3 #3 [<c012f063>] __report_bad_irq+0x24/0x69 [<c012f06a>] __report_bad_irq+0x2b/0x69 [<c012f257>] note_interrupt+0x1af/0x1e4 [<c01cbc97>] acpi_irq+0xb/0x1c [<c012e983>] handle_IRQ_event+0x1a/0x3f [<c012f917>] handle_level_irq+0x63/0x84 [<c01046d0>] do_IRQ+0x4b/0x60 [<c010320f>] common_interrupt+0x23/0x28 [<c01d007b>] acpi_ds_create_operands+0x1c/0xf9 [<c0118f03>] __do_softirq+0x2c/0x75 [<c0118f6e>] do_softirq+0x22/0x26 [<c01191ea>] irq_exit+0x25/0x53 [<c01046d5>] do_IRQ+0x50/0x60 [<c010320f>] common_interrupt+0x23/0x28 [<c01ef3c0>] acpi_idle_enter_simple+0x16d/0x1d9 [<c025bdba>] cpuidle_idle_call+0x49/0x77 [<c025bd71>] cpuidle_idle_call+0x0/0x77 [<c010176c>] cpu_idle+0x48/0x61 ======================= handlers: [<c01cbc8c>] (acpi_irq+0x0/0x1c) Disabling IRQ #9 BUG: soft lockup - CPU#0 stuck for 138s! [syslogd:1952]
If I read that OOPS right, then I got an interrupt ("common_interrupt"), which made the kernel run the ACPI function "acpi_ds_create_operands" and while this executed, I've got another interupt, which killed my for for 138 seconds ...
Shouldn't there some sort of protection about this or is the DSDT of my device just bogus?
Kernel 2.6.26.3
CPU: "Geode(TM) Integrated Processor by AMD PCS"
How to reproduce: press ACPI buttons repeatedly
ACPI related kernel-commandline entries: "pci=noacpi acpi_serialize". The first is vital (no boot without), the second one is an experiment, I got OOPSes without that, too.
