First the USB problem: Has anyone else experienced problems with USB using kernel 2.4.19? I managed to lock my box up entirely just now simply by plugging the USB cable in, other times it will be fine, then a few days ago I had a kernel panic when transferring a large amount of data over the USB. I can't see many problems reported on google, so it may be I've missed something vital from USB support in the kernel or something silly?
I'm running 2.4.19 with a USB Speedtouch modem. Generally it works 24/7 shovelling much data around, but I do get kernel panics when probing or removing modules if I don't do it in the right order. I also get random hangs.
I think I might put those down to SMP - I get a lot of 'apic error on cpu x' messages that generally don't seem to do anything bad but might occasionally cause a hang or panic.
In 2.4.2 I had to patch the usb kernel source for SMP, but not 2.4.19.
Watch /var/log/messages when plugging it in - see what its trying to do. It'll probably find the device, then modprobe something it thinks should handle that particular device. It might be getting it wrong, or maybe you should modprobe that module yourself right after modprobing usb...
