[Pc_Support] 3Ware 6200, Linux 2.6.15, and AEN errors

[Jason Boxman]

Any chance it's just a bad dream?

I've got the latest firmware on a 6200 series 3Ware card.

FE6X 1.02.28.053
ME6X 1.01.00.028
BE6X 1.07.02.005
ME6X 1.01.00.028

After a few hours of running without incident with a 3Ware 7500-4 on a 
separate 64/33 bus than the 6200 is on, I ended up with these fun, fatal 
errors:

3w-xxxx: scsi0: Reset sequence failed.
3w-xxxx: tw_chrdev_ioctl(): Reset failed for card 0.
3w-xxxx: scsi0: Character ioctl (0x1f) timed out, resetting card.
3w-xxxx: scsi0: AEN drain failed, retrying.
3w-xxxx: scsi0: AEN drain failed, retrying.
3w-xxxx: scsi0: AEN drain failed, retrying.
3w-xxxx: scsi0: Controller errors, card not responding, check all cabling.
3w-xxxx: scsi0: Reset sequence failed.
3w-xxxx: tw_chrdev_ioctl(): Reset failed for card 0.
sd 0:0:0:0: rejecting I/O to offline device
EXT3-fs error (device sda5): ext3_find_entry: reading directory #93328 
offset 0
...

I'm checking the drive now for errors with MaxBlaster, Maxtor's tool, but 
I'm coming up clean so far... I fear it's the controller.

Anyone have any thoughts?  I'd rather replace the Maxtor, as hard drives 
are cheap and easy, but there's no point in replacing what's not actually 
broken (likely the hard disk in this case).

Thanks.
