Kernel BUG at ll_rw_blk.c:1194

[Austin Gonyou <austin@xxxxxxxxxxxxxxx>]

This happened when a filesystem got full and was still trying to be
written to by Oracle. 

This is 2.4.20 + snapshot-xfs-2.4.20-2002-12-18+rl2+rmap15b


Here's the oops..

Ksymoops output below.
-------------------

ksymoops 2.4.1 on i686 2.4.20-ag3.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-ag3/ (default)
     -m /boot/System.map-2.4.20-ag3 (default)

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.
