Bugzilla – Bug 127916
kernel crash at (de)registration of USB device
Last modified: 2005-10-17 17:31:46 UTC
while updating and testing PCSC-Lite together with a certain CTAPI driver I ran into the problem that pcscd can crash the kernel while registering the USB device (SC reader). Olaf was able to get some kernel trace and remembered that a patch for the problem was checked in into mainline one? day ago. He built a test kernel which doesn't crash for me anymore. I don't know in which situations this can happen but as it is a really hard crash it should get fixed for 10.0 as well.

This was also discussed on vendor-sec as it seems. Maybe we consider it security related?
are these the final patches? this is a dup of: https://bugzilla.novell.com/show_bug.cgi?id=118756
No, this cant be a dup of bug #118756 because this bug is about a crash in usb while the other bug is about access denied.
