Hi!
Upon shutdown, my system freezes when /proc/dev/usb is unmounted (i.e.
when usbmgr is killed), forcing a manual power off/on.
His happens with kernel 2.4.14 and has plagued me ever since I upgraded to
kernel 2.4.12, IIRC. Please note that there is _no_ problem while the
system is booting or up and running!
Now, how do I debug this to see who is responseable?
My setup is:
* SuSE-7.2 (with usbmgr-0.4.6)
* Linux kernel 2.4.14
* Loaded usb modules: usbcore, usb-ohci, pwc, hid, mousedev.
The only usb device in use is a Philips webcam which works fine.
Loading/unloading the pwc driver works also fine.
However, unloading the usb-ohci freezes the kernel just like
unmounting the usbdevfs filesystem.
Running lsusb (output attached) gives an error message (cannot get config
descriptor 0, Connection timed out (110)) and creates many (about 50)
identical syslog entries like:
kernel: usb_control/bulk_msg: timeout
kernel: usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 486 ret -110
I've attached the following:
1. output of: /proc/dev/bus/devices
2. output of: lsusb
3. syslog messages by usbmgr during boot
4. syslog messages by usb modules (usb.c, usb-ohci.c) during boot
There _are_ some error messages in the usb kernel logs (attached
usb.bootlog). For instance, kusbd tries to load /sbin/hotplug which
doesn't exist.
I'm a bit lost now. Therefore, I'd appreciate any help in howto
further diagnose my problem. Thanks!
Regards, Walter
