Subject: p54usb broken by commit b19fa1f

In testing 2.6.27-rc1, I found that p54usb caused my machine to freeze. A few
times, I was able to use the KDE system status applet to see that the system was
using essentially 100% of the CPU's. One other time, the system responded a 
little - enough for me to see tha wpa_supplicant was consuming 100% of the my 
AMD Turion 64 X2 running an x86_64 kernel. From bisection, the problem is due to

     net: Delete NETDEVICES_MULTIQUEUE kconfig option.

     Multiple TX queue support is a core networking feature.

     Signed-off-by: David S. Miller <davem@...emloft.net>

Obviously, something in the driver cannot handle multiqueues, but I
have not found anything, and I have not been able to get any logged events that
show what is going wrong.

Thanks,

Larry
