Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.
