Well, I've got this one (Asus L5D, x86_64 kernel):
============================ [ BUG: illegal lock usage! ] ---------------------------- illegal {in-hardirq-W} -> {hardirq-on-W} usage. hwinfo/3398 [HC0[0]:SC0[1]:HE1:SE0] takes: (&list->lock){++..}, at: [<ffffffff8046d301>] unix_stream_connect+0x371/0x440 {in-hardirq-W} state was registered at: [<ffffffff8024bdaa>] lock_acquire+0x8a/0xc0 [<ffffffff8047347f>] _spin_lock_irqsave+0x3f/0x60 [<ffffffff80406e72>] skb_dequeue+0x22/0x70 [<ffffffff881c97b1>] hpsb_bus_reset+0x61/0xb0 [ieee1394] [<ffffffff8822e986>] ohci_irq_handler+0x416/0x830 [ohci1394] [<ffffffff8026208b>] handle_IRQ_event+0x2b/0x70 [<ffffffff80263a03>] handle_level_irq+0xb3/0x120 [<ffffffff8020c6ec>] do_IRQ+0x5c/0x80 [<ffffffff80209d60>] common_interrupt+0x64/0x65 irq event stamp: 29916 hardirqs last enabled at (29915): [<ffffffff802893f5>] kmem_cache_free+0xb5/0xd0 hardirqs last disabled at (29914): [<ffffffff802893d0>] kmem_cache_free+0x90/0xd0 softirqs last enabled at (29912): [<ffffffff802342fe>] __do_softirq+0xbe/0xd0 softirqs last disabled at (29916): [<ffffffff80472ac1>] _spin_lock_bh+0x11/0x50
