Stefan Richter ae1e535579 firewire: deadline for PHY config transmission ... If the low-level driver failed to initialize a card properly without noticing it, fw-core was blocked indefinitely when trying to send a PHY config packet. This hung up the events kernel thread, e.g. locked up keyboard input. https://bugzilla.redhat.com/show_bug.cgi?id=444694 https://bugzilla.redhat.com/show_bug.cgi?id=446763 This problem was introduced between 2.6.25 and 2.6.26-rc1 by commit 2a0a259049 "firewire: wait until PHY configuration packet was transmitted (fix bus reset loop)". The solution is to wait with timeout. I tested it with 7 different working controllers and 1 non-working controller. On the working ones, the packet callback complete()s usually --- but not always --- before a timeout of 10ms. Hence I chose a safer timeout of 100ms. On the few tests with the non-working controller ALi M5271, PHY config packet transmission always timed out so far. (Fw-ohci needs to be fixed for this controller independently of this deadline fix. Often the core doesn't even attempt to send a phy config because not even self ID reception works.) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>		2008-06-19 00:12:35 +02:00
