I apologize for sending this to both the Linux kernel mailing list as
well as the Linux-XFS mailing list. I am sending this to the lkml
because it's a kernel bug report. I'm sending this to the Linux-XFS
mailing list because I do not know if "try_to_free_buffers+130/240" in
the Call Trace has anything to do with changes that the XFS team has
done on the Linux kernel.
I got kernel BUG reports in my system logs[1] and dmesg[2] four times
today. The first time it happened with process kswapd, the second with
process httpd (of Apache), the third and fourth with ssh which I was
firing up through wterm. They happened all within a fairly short period
of time: the first at 16:02:05, the second at the same time, the third
at 16:03:51 and the fourth at 16:03:53.
I am running Linux kernel 2.4.19-rc2-xfs (CVS snapshot 20020718),
compiled using the current gcc-3.1 Debian packages from Sid (gcc version
3.1.1 20020703 (Debian prerelease) according to `gcc-3.1 -v`), on an AMD
Duron/850MHz. This system has been running continuously using this
kernel for 7 days 22:13, according to uptime. I didn't do anything
special this afternoon when all four kernel BUG incidences occured.
Would any of the kernel or XFS developers want me to do anything to
perhaps help debug this situation? I intend to move this system up to
2.4.19-rc3-xfs (CVS snapshot as of today), otherwise.
Thanks a lot in advance.
