Kernel 2.4.9 locks up solidly with USB and SMP

Kernel 2.4.9 locks up solidly with USB and SMP

[Andy Stewart]

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,

Use the uhci module instead and it ought to be better

Using the uhci module has indeed solved the problem.

Thank you!

I tried this and did not see any printout on my screen.  I waited over a 
minute after the lockup before rebooting.  There's nothing in the system 
log file, either.  Just hard lockup.  :-(

Thank you for the suggestion.

Try to convert lockup into oops. Sometimes slab poisoning helps.

Well, someone will undoubtedly suggest to try JE uhci, do that too.
