Summary: "bad: scheduling while atomic!" flood after IDE error Kernel Version: 2.5.75 Status: NEW Severity: normal Owner: alan@lxorguk.ukuu.org.uk Submitter: rl@hellgate.ch
This problem has been reported on LKML for 2.5.74. 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):
