I've patched a fresh kernel 2.4.20 with JFS 1.1.2 tarball from
<http://oss.software.ibm.com/jfs/>. Once the system was under load, the
kernel oopsed and any access to the JFS partitions deadlocks. I'm
including the decoded oops below.
Are there problems with the 1.1.2 code? Or using it with 2.4.20? Any
hints?
