I saw several similar reports.
Please, submit me the output of the "print *mp" in the same frame.
Also, I'm interested in kernel config.
Is the problem reproducible ?
It seems now that any time I compile openoffice the system will
eventually panic. Other disk intensive jobs, like my nightly photo-album
update, may or may not trigger it. I currently have two dumps for
6.1p10. I thought this might be failing hardware because the system has
worked fine for nearly a year, but the fact that it panics on the same
line of code every time makes me wonder.
Here are the prints from the latest dump:
