Ok, its my first post here, sorry for the lenght of this:
Basically this is the situation. I have a pent100, with 16megs of ram,
running redhat6.2 and kernel 2.4.5. The box is used as a webserver, which
does not get much traffic at all, the site is acutally being built right now.
I also have a d-link 2port usb card I installed, so that I can use the
usb-ibmcam model2 I have to run a small webcam. I have used two programs to
capture the image (the ibmcam is seen as a v4l device) vgrabbj and webcam
from the xawtv package, the same crash occurs with both, so it doesn't seem to
be their fault. I would really really really like to solve this, i am willing
to try patches etc.. FYI, yes I do see that there are two USB controllers, the
first, (the VIA one) must be enabled in the bios, otherwise the one I added
will not work. The VIA one is just a chip, i have no idea why it is in the
machine, there are no ports for it just the chip. odd?? I think so.
The error I get, which completly takes the machine down is:
kernel BUG at usb-ohci.h:466!
Now the juicy bits:
the kernel error:
usb-ohci.c: unlink URB timeout
ibmcam_stop_isoc: usb_unlink_urb() error -110.
usb-ohci.c: unlink URB timeout
ibmcam_stop_isoc: usb_unlink_urb() error -110.
