Yes, well known RELENG_4 -> 6 (maybe even 5) regression. Same here with
acd0: CDRW <CD-W540E/1.0C> at ata1-master UDMA33
Worked fine under RELENG_4, fails to wait for completion under RELENG_6.
indeed, the two routines are different: in RELENG_4
static int
acd_get_progress(struct acd_softc *cdp, int *finished)
{
int8_t ccb[16] = { ATAPI_READ_CAPACITY, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0 };
My memory is rusty here, but I thought that a TUR was the canonical way
to test if the operation is complete, and get progress as a side effect.
I see that until rev 1.85, this function used a plain REQUEST_SENSE,
which was definitely wrong. There has to be some way that a
WHQL-qualified disc burner will report this information reliably.
