So, today and a few days ago (prior to upgrading FC6 to FC7, partially
sparked by this issue to see if it would resolve it) my USB controller
in my laptop has been going wonky. Occasionally, on startup, just before
the part with the blue "Fedora" word, it would spit out a whole lot of
error messages, and from then on my USB ports would not work. Sometimes
it doesn't happen then, but later on, sometimes a couple minutes after
login. Also, when I reboot after this happens, sometimes the laptop gets
stuck on the BIOS boot screen and won't respond, forcing a hard
shutdown. I am led to believe this is related to overheating, as it is
very hot and humid today, and probably was a few days ago when this
happened before.
Anyway, in hopes that there is a software or perhaps bios reason at
fault as well, here is an example of what dmesg spits out when the fail
happens, and my IRQ setup thing:
[grinnz@localhost ~]$ dmesg

One thing I would like to point out is that I am not using eth0 (my
wired connection) currently, but it seems to be having issues as well,
as NetworkManager will attempt to connect to the wired network (???)
through eth1 perhaps? Failing this it correctly switches to connecting
to a wireless network, but then occasionally still says Connected to
Wired Network...
Now I am concerned (possibly baselessly, as I have no knowledge of IRQs)
that it may be related to all the
devices on IRQ 16. (cardbus, usb1, eth0, and my video card; note I don't
use cardbus ever)
Thanks for any help,
-Dan
