quick reparse of the data you've given.  ata command 0x30 (write
sectors) timed out after 1 minute at lba 231760 which is safely under
8GB.  the status (register 7) is 0x58 which is
	0x08	Drq		/* waiting on your data */
	0x10	Serv
	0x40	Drdy

but the lba read back (assuming it's correct) is 231769.  so some
progress has been made -- indicating we're getting some interrupts,
but somehow we've missed one and stalled out.

the real problem is that data > limit by 236kb.  i'm not sure how this
could happen.  something looks very wrong.
