"MODE_SENSE_BIG command timeout - resetting" at boot

Wed May 12 06:28:07 PDT 2004

Hi,

I'm having the following problem on a new machine I just installed.

At boot time, exactly 20 times, during device probe:
	acd0: MODE_SENSE_BIG command timeout - resetting
	ata0: resetting devices .. done
Then:
	acd0: CDROM <SAMSUNG CD-ROM SC-152G> at ata0-master PIO4

If I try to mount a CD afterwards, I get the following sequence
followed by an I/O error return:

(next 2 lines 4 times)
acd0: TEST_UNIT_READY command timeout - resetting
ata0: resetting devices .. done
(next 2 lines 4 times)
acd0: PREVENT_ALLOW command timeout - resetting
ata0: resetting devices .. done
(next 2 lines 8 times)
acd0: TEST_UNIT_READY command timeout - resetting
ata0: resetting devices .. done
(next 2 lines 8 times)
acd0: PREVENT_ALLOW command timeout - resetting
ata0: resetting devices .. done
(next 2 lines 2 times)
acd0: TEST_UNIT_READY command timeout - resetting
ata0: resetting devices .. done

OTOH, it works perfectly with atang when booting a -current install CD.

Full dmesg below. Any ideas?
