Hm when I try this on the v3.7 I get this:

PCI: enabling device 0000:00:0d.0 (0100 -> 0102)
sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 28
sym0: No NVRAM, ID 7, Fast-40, LVD, parity checking
sym0: SCSI BUS has been reset.

So IRQ 28 instead of 27???

Then the device does not work (no clue why it's like that)
but it's trying IRQ 28 atleast.

On v3.8-rc5 I get this:

PCI: enabling device 0000:00:0d.0 (0100 -> 0103)
sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 28
sym0: No NVRAM, ID 7, Fast-40, LVD, parity checking
sym0: request irq 28 failure
sym0: giving up ...

OK, so half-guessing I've reproduced part of the problem
atleast...

Yours,
Linus Walleij
