2.5.64-ac3: Crash in ide_init_queue

Hija,

my new motherboard with KT400 chipset oopses in ide_init_queue on bootup
with the follow output:

Oops: 0000

Code:  Bad EIP value.

The system doesn't have a harddrive, both channels are enabled,
the second bus has a TOSHIBA Combo DVD/CD-R SD-R1002 conntected
as master device. Disabling the secondary channel channel fixes 
the problem.

Should I bugzill it?

It's compiled into the kernel but unused since there's no harddrive in
the machine. I'll remove it from the config and retry.

Nope, same problem without tcq.

Please double check, TCQ is the only way that ide_init_queue() would end
up with NULL EIP.

You could make the ide_dma_queued_on() conditional, ala:

#ifdef CONFIG_BLK_DEV_IDE_TCQ_DEFAULT
	if (HWIF(drive)->ide_dma_queued_on)
		HWIF(drive)->ide_dma_queued_on(drive);
#endif

Yep this was a nobrainer of mine. As stated in a followup mail, this
problem went away and a different IDE problem stepped up.
