If you get messages like "code XXX > ignored", where "XXX" is a number, then you may have a memory conflict. it dumps core but I see a large number of ignored messages before it does. > In theory, PCI devices can share IRQs.

With luck, the USB > device can share IRQs (but I don't know this for a fact). Its on 11. Or are you saying that it too will allocate daughter irq to attached devices, and I need to be careful about the 3/5/7/9 set which I now depend on as my 'pool' for non-wired things? What do I try to clear up the mem conflicts for pcic next? I'm tempted to try leaving it to the kernel to find these and not wire it to 5, but I fear it will bounce back into PIO mode and I'll be back on freezes (My guess is that Windows uses PIO, and is able to avoid this whole mess) cheers -George To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
