Subject: Kernel 3.17.x Attaching Keyspan 4-Port Serial to USB Adapter Causes
Kernel Panic
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 ...
