Subject: Kernel 3.17.x Attaching Keyspan 4-Port Serial to USB Adapter Causes Kernel Panic
Date: Sat, 20 Dec 2014 16:08:20 -0800 [thread overview]
Message-ID: <54960F74.1050608@pacbell.net> (raw)
On a new Gentoo based system with Kernel.org Kernels 3.17.4 to 3.17.7
when I physically plug the Keyspan 4-Port Serial to USB adapter into a
usb port my system freezes with a "unable to handle kernel NULL pointer
deference" message.
My old system (also Gentoo based with Kernel.org 3.17.4) does not have
this issue. Both systems are using the USB_SERIAL_KEYSPAN_USA49W
driver module.
I tried booting into single user mode, using modprobe to load
USB_SERIAL_KEYSPAN_USA49W. lsmod shows the driver. When I pluged the
device in I receive the system freeze. Below is what I copied off the
console ...
