SubjectKernel 2.4.9 locks up solidly with USB and SMP
Date

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,
