Dell ieee1394 driver for RHEL4 seems pretty stable in my test

I plugged a cheap pci 1394 card (VIA Technologies) onto one of my
RHAS4.2 servers. Build and install the ieee1394 driver using DKMS and
Dell rpm, reboot the server and it automatically pick up the 1394 card
and load the drivers. I dumped around 400GB data from an external
firewire drive to the server attached scsi disks. It took 5hr and 20min.
There were no server crashes, lockups, scsi io errors. The setup seems
pretty stable. 

The only drawback is it's slowness. The IO throughput is around 22MBs.
On a similar setup with on-board USB2 ports, I got close to 40MBs
throughput. I don't know if this is due to the card cheapness, the
driver or something else. It will be great if Dell folks can show us
their test results. 

Anyway, 22MBs seems pretty good to me. I really appreciate Dell kernel
developers' efforts to make it work. Of course, if you guys can improve
it to 40MBs, that will be even awesome. :)

Thanks,

Jin

http://ftp.us.dell.com/rmsd/ieee1394-2.6.9-rhel4-multiarch-2.tar.gz
is Dell's release of 1394 tested on RHEL4 on our Precision workstations.
We fixed a bunch of bugs; there may well be more lurking but if so we
didn't encounter them.  Use at your own risk of course.

Thanks,
