I think I have seen it at least with 2.5.73, too. The system looks okay, then, usually hours later (if at all, it's a rare event), something freezes the system for several seconds and triggers a flood of those call traces (many of them per second). It seems an IDE error causes it. A 2.5.75 trace (the call stack is always the same): Jul 12 13:08:47 [kernel] hda: dma_timer_expiry: dma status == 0x61 Jul 12 13:09:02 [kernel] hda: timeout waiting for DMA Jul 12 13:09:03 [kernel] ide0: reset: success Jul 12 13:09:03 [kernel] bad: scheduling while atomic! - Last output repeated 103 times - Jul 12 13:09:51 [kernel] Call Trace: Jul 12 13:09:51 [kernel] [] default_idle+0x0/0x40 Jul 12 13:09:51 [kernel] [] schedule+0x500/0x510 Jul 12 13:09:51 [kernel] [] poll_idle+0x2a/0x40 Jul 12 13:09:51 [kernel] [] apm_cpu_idle+0xa3/0x140 Jul 12 13:09:51 [kernel] [] apm_cpu_idle+0x0/0x140 Jul 12 13:09:51 [kernel] [] default_idle+0x0/0x40 Jul 12 13:09:51 [kernel] [] cpu_idle+0x38/0x40 Jul 12 13:09:51 [kernel] [] rest_init+0x0/0x30 Jul 12 13:09:51 [kernel] [] start_kernel+0x138/0x140 Jul 12 13:09:51 [kernel] [] unknown_bootoption+0x0/0x100 Jul 12 13:09:51 [kernel] bad: scheduling while atomic! - Last output repeated 144 times - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
