Subject: [2.5.74] bad: scheduling while atomic!
Date: Fri, 4 Jul 2003 17:34:07 +0200 [thread overview]
Message-ID: <20030704153407.GA3540@k3.hellgate.ch> (raw)
I haven't had the time to investigate this, so I don't have much
information to share beyond the trace below. I think I have seen this at
least with 2.5.73, too. The system looks okay, then, usually hours later
(if at all, it's a rare event), something triggers a flood of those call
traces (many of them per second).
The syslog seems to suggest it might be related to IDE DMA:
Jul 4 17:17:28 [kernel] hda: dma_timer_expiry: dma status == 0x61
Jul 4 17:17:44 [kernel] hda: timeout waiting for DMA
Jul 4 17:17:44 [kernel] [<c0107000>] default_idle+0x0/0x40
Jul 4 17:17:44 [kernel] bad: scheduling while atomic!
Compiler is gcc 3.2.3.
bad: scheduling while atomic!
