[2.6.8.1] OOPS in page_waitqueue
From: Set Norman
Date: Sun Sep 05 2004 - 17:33:54 EST
Kernel is 2.6.8.1 (monolithic), OOPS related to page_waitqueue.
Found this OOPS in my syslog a couple of hours ago. Don't know if it is of any
significance, haven't seen it on lkml. Let me know if further information is
required.
System is debian unstable, Pentium II @ 700. Has been running every 2.6 kernel
I have tried without problems. This particular one had been up and running for
almost two weeks before the OOPS. The system is/was not under any significant
load.
Thanks,
