Which revision? The 1542B that I have doesn't need this delay. The
probe string will tell you the revision.
: As Graham Menhennitt said: "Could somebody please commit this change"
Been there, done that. Justin and I have been talking about a better
way to deal with this problem than putting in a magic delay. There
may be another round of patches for the folks with the problem 1542B
cards to test.
: fuzz: {1} diff /sys/dev/aha/aha.c.orig /sys/dev/aha/aha.c
diff -u generally produces better results. Also, I have a better
comment stating that a delay to 1000 works, but 10mS is very long in
card time, but very short in probe time. There was a similar delay in
the old driver in places, but I've not looked closely enough to know
if this was one of the places or not.
