SubjectFirewire still bOrken (sigh)
From
Date
This is mostly for Ben Collins (although any and all are encouraged to
take a peek). After reading LKML for test2 and all of the work that
went in, I hoped firewire would be happy. Unfortunately not. The good
news is that a lot of other stuff is happy.
(for instance, I am typing this to you from `uname -r`== 2.6.0-test3).

To be sure I didn't have any wacky configurations happening, I wiped /
and re-installed RH9, then module-init-tools, and rebuild 2.6.0-test3.
dmesg gives me the following:
Linux version 2.6.0-test3 (root@localhost.localdomain) (gcc version
3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Fri Aug 15 15:56:43 MDT 2003
