VIA Firewire still broken in 2.6.5 (also broken in 2.6.4, worked in 2.6.3)

[Felix von Leitner]

In 2.6.4, the kernel would detect my cold plugged Maxtor disk, but then
freeze and eventually time out trying to mount the file system on it in
the boot process.

In 2.6.5, largely the same, but the kernel works when the disk is hot
plugged in after the boot process.  Having it plugged in during the boot
process still fails, and unplugging and replugging it after the boot
process still fails.

After a few write accesses on the file system, however, 2.6.5 panics.

Is this a known problem?  Anyone working on it?

Yup.  There seems to have been some progress in this regard in the
linux1394 mailing lists and SVN repository, but it's still a bit
unstable.

Personally, I've been using the 2.6.3 ieee1394 sources in newer kernel
releases, and it's been working very well.  Perhaps we should revert
drivers/ieee1394 to the 2.6.3 state until the problems are addressed
in the linux1394 repository, to only then have it merged here.
What we have now was a merge of a non-functional state of the tree,
which servers nobody.

I can easily provide a patch to restore the working state, if people
think this would be a good idea.  Just say the word.
