I'm running Fedora Core 2 and on occasion I get a protection fault which
locks a file on the disk due to a spinlock not being unlocked
(apparently). This is from a custom kernel where the only difference is
I set it to use Athlon 64 specific optimizations vs. generic x86-64.
The same problem happens on the stock 2.6.8-1.521, 2.6.5-1.358, and a
custom built 2.6.9-rc4.
Anybody else seeing this or have a fix for it?
Thanks!
