Description Niels Walet 2003-04-18 12:48:48 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003

Description of problem:
This might be a kernel problem:
After a reboot (an a kernel upgrade), I suddenly lost support for usb.
The issue seems to be that usb is not listed in /proc/devices,
even though the io-ports can be seen in /proc/ioports.  
This happens in kernel version .4.18-27.8.0smp, but I am a little confused by
the fact that I cannot regress to the previous kernel!

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:


Actual Results:  Looking at the script, if usb is missing in devices usb support
will not be loaded... I am not sure what the kernel issue is that shows usb
support in /proc/devices.

and dmesg after a boot with it failing ti see the USB ?

Comment 4 Pete Zaitcev 2003-06-06 21:15:03 UTC
Alan's right, we need a decent dmesg. Please attach it instead of dropping
into the comments box.

Another thing, please upgrade to 2.4.20-18.8.
