Kernel 2.4.9 locks up solidly with USB and SMP

[Andy Stewart <andystewart@mediaone.net>]

Hello, 

Please CC any replies to me directly.

With kernel version 2.4.9, my system locks up solidly when I run with SMP 
enabled and attempt to print anything to my USB printer.   I have seen 
this behavior for the last few kernel revs.

SMP without USB seems to work properly.  USB in uniprocessor mode is also 
working properly.

I have usbcore and usb-uhci loaded as modules.

My motherboard is a Tyan Thunderbolt S1837 with two Intel Pentium 3s at 
450 MHz. and 256 MB of memory.  The output from "lspci -v" is appended to 
this e-mail.  I'm not sure what other information I could provide that 
would help isolate this problem.  I would be happy to provide more - 
please ask.

It is unclear to me if I am doing something wrong, if this is a bug in the 
kernel, or a bug in my hardware.  Any help would be most appreciated.

Thanks in advance,
