Summary: oops bad scheduling while atomic Kernel Version: 2.5.68 sched-2.5.68-B2 Preemptible Kernel Status: NEW Severity: low Owner: rml@tech9.net Submitter: builderbert@snet.net
Distribution: I was just doing a compile of gcc 3.2.3 and got the following oops at some point during the compile (not exactly sure where -- I killed the job and then later checked dmesg).
Hardware Environment: AMD Duron 900 VIA VT8363/8365 VT82C586B PIPC Bus Master IDE
Software Environment: RedHat 7.3 Rusty's modutils
Problem Description:
oops below (when restarting, I also noticed /dev/hda2 had been umounted...)
