Subject: PROBLEM: Kernel Bug on USB unplugging (Elo TouchSystems CarrollTouch 4500U)
On unplugging this USB Touchscreen, everytime I get either:
[ 161.596055] BUG: unable to handle kernel NULL pointer dereference at 00000015
[ 161.596093] IP: [<c10c92b0>] get_next_timer_interrupt+0x80/0x270
or
[ 155.892061] BUG: unable to handle kernel paging request at 30303046
[ 155.892101] IP: [<c10d13da>] get_next_timer_interrupt+0x8a/0x290
and then panic and the system is unresponsive.
Tried several kernels, without change.
The 4.4.11 tested is Vanilla with Debian config, the 4.5 is a Debian Kernel with their patches.
Output of oops on 4.4.11:
