Hi Mike, with the latest git snapshot the cciss driver hangs during initialisation. Enabling debug output I get: cciss0: <0x3230> at PCI 0000:06:00.0 IRQ 4338 using DAC Sending cff0000 - down to controller cciss: FIFO Empty read cciss: Read cff00000 back from board Sending cff0000 - down to controller cciss: FIFO Empty read cciss: Read cff00002 back from board LUN Data -------------------------- Sending cff0000 - down to controller cciss: FIFO Empty read cciss: Read cff00000 back from board blocks= 286677120 block_size= 512 Sending cff0000 - down to controller cciss: FIFO Empty read cciss: Read cff00002 back from board heads=255, sectors=32, cylinders=35132 Sending 5103000 - down to controller and then the machine hangs. I'll try to investigate, but as I'm no expert in cciss my results might be limited. Looks like one of your recent fixes broke it; 2.6.21 worked fine.
