2.6.0-test1-ac3 Firewire

[Yu Ming]

Hi,
I am running RedHat 9.0 with kernel 2.6.0-test1-ac3, everything works fine
with 1394 firewire connected with SONY DVD RW DRU-500A, except of the
following annoying messages from dmesg.
When I plug or unplug the 1394 fireware, I got from dmesg,
ohci1394_0: SelfID received, but NodeID invalid (probably new bus reset
occurred): 0000FFC0

When I test the 1394 DVD burner read speed, 
readcd dev=1,0,0 f=/dev/null
I got from dmesg,
Debug: sleeping function called from invalid context at

 And the messages go on repeatedly.

I also got from dmesg,
UDP: short packet: From 0.0.0.0:68 288/282 to 255.255.255.255:67
repeatedly.

occasionally(very rarely), I got from dmesg,
spurious 8259A interrupt: IRQ7
