hi, not sure where to post this... had an imac ppc for long time, but some time back found my ipod and itunes would lockup during sync'ing i assume hardware failure, but whilst exploring this, due to someone else on macrumours experiencing similar, i found something odd.. it would appear, that what happens is a USB card reader i have (using std apple driver), somehow locks up the firewire devices. Jun 5 18:27:01 mymac kernel: /SourceCache/AppleFWOHCI/AppleFWOHCI-252.4.0/AppleFWOHCI.cpp 3539: ERROR: FireWire (OHCI) Apple ID 31 built-in: handleUnrecoverableErrorInt i can now reproduce using these steps: a) have ipod and isight plugged in b) turn on camera (ichat), start sync ipoc in itunes c) plug in card reader into USB * all ok at this point, d) unplug card reader * everything stops, itunes and ipod lock up, ichat/isight freeze * above error in system.log e) unplug isight, plug it back in * itunes/ipod restart copying, isight works any ideas? im hoping i can work around, but interested if this is i) card reader driver fault ii) isight fault iii) firewire fault note: latest versions of osx/firmware are in place note: the unplugging of card reader, is just to reproduce... i believe i had similar without unplugging, symptoms however were identical. can anyone else reproduce this? a known bug in osx?
