I booted with 'root=/dev/sda3 debug memory_corruption_check=1 devres.log=1 debug_objects debugpat acpi.debug_layer=0x00410002 acpi.debug_level=0xffffffff acpi=off noapic nolapic irqpoll pci=noacpi' and issued 'xset dpms force standby'. After touching the mouse the system locked for about a minute, and the wireless stopped working. Here's the log portion, I hope it provides a hint of some sort: [ 182.891400] ****** b43: B43_MMIO_MACCTL 0x840A0503 [ 182.891409] ****** b43: SSB_TMSLOW 0x20150000 [ 258.299027] irq 10: nobody cared (try booting with the "irqpoll" option) [ 258.299038] Pid: 0, comm: swapper Not tainted 2.6.28-rc5 #15 [ 258.299043] Call Trace: [ 258.299062] [<c0148d9a>] __report_bad_irq+0x24/0x69 [ 258.299071] [<c0148da1>] __report_bad_irq+0x2b/0x69 [ 258.299080] [<c0148ec8>] note_interrupt+0xe9/0x12d [ 258.299090] [<c014976d>] handle_level_irq+0x87/0xba [ 258.299101] [<c010564e>] do_IRQ+0x89/0x9f [ 258.299109] [<c0103ea8>] common_interrupt+0x28/0x30 [ 258.299119] [<c0125406>] do_softirq+0x37/0x4d [ 258.299127] [<c0125301>] __do_softirq+0x62/0x130 [ 258.299135] [<c0125406>] do_softirq+0x37/0x4d [ 258.299142] [<c0105653>] do_IRQ+0x8e/0x9f [ 258.299150] [<c0103ea8>] common_interrupt+0x28/0x30 [ 258.299161] [<c0108682>] default_idle+0x2f/0x4c [ 258.299168] [<c0101a20>] cpu_idle+0x63/0x77 [ 258.299173] handlers: [ 258.299176] [<f7906455>] (b43_interrupt_handler+0x0/0x1b7 [b43]) [ 258.299212] Disabling IRQ #10 [ 258.315148] b43-phy0: Radio hardware status changed to DISABLED [ 258.315160] b43-phy0: ******** B43_B43_MMIO_RADIO_HWENABLED_HI 0xFFFFFFFF [ 258.342341] kobject: 'rfkill0' (f43b7d78): kobject_uevent_env [ 258.342367] kobject: 'rfkill0' (f43b7d78): fill_kobj_path: path = '/class/rfkill/rfkill0' [ 258.342418] kobject: 'ssb0:0' (f40dfcd8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:02.0/0000:02:00.0/ssb0:0' [ 258.391951] [ 258.391956] ================================= [ 258.391964] [ INFO: inconsistent lock state ] [ 258.391971] 2.6.28-rc5 #15 [ 258.391975] --------------------------------- [ 258.391980] inconsistent {in-hardirq-W} -> {hardirq-on-W} usage.
