3ware 9500 locks up on 6.0-stable!

[Alfred Perlstein]

Hello.

I was running a 3ware 9500 controller:

//max> /c0 show driver
/c0 Driver Version = 3.50.00.016

//max> /c0 show model
/c0 Model = 9500S-4LP

//max> /c0 show firmware   
/c0 Firmware Version = FE9X 2.06.00.009

//max> /c0 show bios
/c0 Bios Version = BE9X 2.03.01.051

I recently upgraded it to 6.x and experienced many hard lockups.

What I see in the logs looks like this:

Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Request Requeued
Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Retrying Command
Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Request Requeued
Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Retrying Command
Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Request Requeued
Jan  9 13:14:50 max kernel: (da0:twa0:0:0:0): Retrying Command
Jan  9 13:17:25 max kernel: twa0: INFO: (0x04: 0x000c): Initialize started: unit=0

Under FreeBSD 6.0 is seems to lock up shortly after the "Initialize
started" message.

Under 5.4 I get more of these messages:
Jan  9 13:18:27 max kernel: (da0:twa0:0:0:0): Request Requeued
Jan  9 13:18:27 max kernel: (da0:twa0:0:0:0): Retrying Command
Jan  9 13:18:42 max kernel: (da0:twa0:0:0:0): Request Requeued
Jan  9 13:18:42 max kernel: (da0:twa0:0:0:0): Retrying Command
...

And things seem fine... for now... there is currently a rebuild
and it's 12% complete.

Additionally it seems that under FreeBSD 5.4 and 6.0 the 3dm web
tool does not function.

Anyhow, I would love to be of help to get this resolved so that
3ware works on 6.x.  I can make time in late evenings EST (after 5
or 6 PM) to run any diagnostics or patches.

Please let me know!

thank you,
