Coudl you please remove the following code (or similar)
from the ata_irq_request() function and see whatever the crash still
happens? It could very well we that hwgroup->drive isn't
initialized during boot under seom cirumstances.



		if (hwgroup->drive->channel->sharing_irq && ch != hwgroup->drive->channel && 
ch->io_ports[IDE_CONTROL_OFFSET]) {
			/* set nIEN for previous channel */
			/* FIXME: check this! It appears to act on the current channel! */

			if (ch->intrproc)
				ch->intrproc(drive);
			else
				OUT_BYTE((drive)->ctl|2, ch->io_ports[IDE_CONTROL_OFFSET]);
		}
