Report being fixed with Dell firmware update v2.8.1.7692 (build 7692).

Tested OK with Hardy 9.04 and Karmic 9.10 on Dell PowerEdge 2550 with PERC 3/Di (hw pci id 1028:0002).

Problem is in firmware: "PERC has no 64 bit scsi passthrough function."

Workaround for pre-v.2.8.1.7692: downgrade performance with kernel (2.6.25.4) options:
"aacraid.dacmode=0 aacraid.nondasd=0 aacraid.expose_physicals=0"

PowerEdge 2550 PERC Firmware v2.8.1.7692 is available on Win32 floppy writer program only. I extracted files from floppies http://esa.hakkinen.com/konehuone/dell2550/ and used FreeDOS to flash firmare.

Patch first motherboard BIOS and reboot, then PERC firmware, otherwise bricking will happen. It's good idea to have v2.8.x firmare already patched before this update. readme.txt says v2.6 is minimum, other sources recommend updating from v2.6/v2.7 to 2.8.0 first. Seek ftp://ftp.us.dell.com/sysman/ and dell support site for firmware updates.
