Subject: [LIBATA BUG] sr.c: TEST_UNIT_READY error
Date: Thu, 01 Feb 2007 14:15:02 +0800 [thread overview]
Message-ID: <1170310503.5166.17.camel@localhost.localdomain> (raw)
In-Reply-To: <45BEF61F.7000400@garzik.org>
Hi,
TEST_UNIT_READY in get_capabilities (drivers/scsi/sr.c line 743, or
see below) always returns error.
---------------- code begin -----------------------------
retries = 0;
do {
memset((void *)cmd, 0, MAX_COMMAND_SIZE);
cmd[0] = TEST_UNIT_READY;
the_result = scsi_execute_req (cd->device, cmd, DMA_NONE, NULL,
0, &sshdr, SR_TIMEOUT,
MAX_RETRIES);
retries++;
} while (retries < 5 &&
(!scsi_status_is_good(the_result) ||
(scsi_sense_valid(&sshdr) &&
sshdr.sense_key == UNIT_ATTENTION)));
---------------- code end -----------------------------
I debugged all kernel versions from 2.6.17 to 2.6.20 on several AMD
and other vendor's PATA/IDE controllers, and I get the_result==0x8000002
and retries==5; on silicon image 3132, i get the_result=0x2eb.
Does 0x8000002 mean ((DRIVER_SENSE << 24) | SAM_STAT_CHECK_CONDITION)?
what's wrong?
Conke
