reading a file from an smbfs causes this oops, then the smbfs won't
unmount.
traversing the filesystem is fine, but reading data is not. first 2=20
oopses are from autofs-mounted shares (nt4), and the last is a
hand-mounted fs (smbd on localhost). i don't suspect that matters
much, though.
this looks like the exact same problem reported against 2.5.19 in
`PROBLEM: Kernel 2.5.19 oops when copying files from SMBFS fs to'.
thanks.

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
