I'm attempting to use XFS on an embedded mips32 system running the 2.4.25
kernel, and am running into some kernel panics. Here are three different
scenarios with different (though 100% reproducible) panics. In all situations,
XFS is compiled into the kernel (but no other XFS options, except for case
(3)). I've included the kernel oops message as well as the version run through
ksymoops for each case at the end of this message.
1) UDF Read Filesystem is also compiled into the kernel; kernel panics when
kernel is loading (last printouts:
Journalled Block Device driver loaded
udf: registering filesystem
SGI XFS with no debug enabled
...then the panic...
2) UDF Filesystem NOT compiled into the kernel, kernel (and nfs-mounted root
fs) load properly, I can successfully
create an XFS filesystem on a partition using mkfs.xfs, I can successfully
mount the XFS partition (various combinations
of mount options work), I can successfully 'ls' the empty mount point. But
when I try to create a file or directory in the XFS partition, the kernel
panics.
3) UDF Filesystem NOT compiled into the kernel, XFS Tracing support and
Debugging support ARE enabled. Panics at kernel load time (final print
statement is "SGI XFS with tracing, debug enabled"), with a different trace
than in (1).
For reference, in (2), when the kernel successfully loads, the next message
after "SGI XFS with no debug enabled" is "pty: 256 Unix98 ptys configured".
The XFS source is stock 2.4.25 kernel source, which works fine for me on an
x86; and with no XFS enabled, I haven't seen any other problems on the embedded
board. Any ideas on where I can start trying to debug this?
Thanks,
Josh
Here are the kernel panics and ksymoops traces for the above cases.
