Adaptec 2810SA problems

Hi all,

I bought an Adaptec 2810SA with 8x250GB disks last month (PCI card). It ran for about one week, and then one disk got degraded. I couldn't get it to work again, it seemed, so replaced the disk. However, recovery still doesn't work.

Now, when I start a 2.6.7 kernel, I get this: (line starts with only the second, all within the same minute)

02:Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0

I have four questions:
1) the kernel says: aacraid: Host adapter appears dead
Do you think that the controller is really dead, or how can I check that? From BIOS, I can see the discs controlled by the card
2) Would upgrading the firmware version 7211 to 7244 help in this situation? Anyone experience with that.
3) Can I upgrade the firmware using wine (it would be nice when adaptec would describe that procedure somewhere) or do I really need to boot DOS from floppy first?
4) Probably there is a kernel bug when this exception situation is handled.

I hope someone can help me save the 500GB of data already on the disks.

Thanks in advance,
