Subject: kernel BUG at fs/sysfs/symlink.c:87 on 2.6.12-rc1-mm4
Date: Mon, 4 Apr 2005 20:27:21 +0200 [thread overview]
Message-ID: <fe726f4e05040411273256c98f@mail.gmail.com> (raw)
Hi,
This just jumped on my dmesg. It happens when you take the usb
'network' cable out of the machine and then plug it back in. The usb0
interface is up.
On earlier kernels it just wouldn't accept the usb address given, but
on -mm4 this bug comes out.
This also has the side-effect of killing USB until reboot.
