Public bug reported:
Binary package hint: kernel-image-2.6.27-3-generic-di
I have installed 8.10 on my Lenovo Thinkpad T61p. If I use the laptop
on its own, it runs for days (and is fabulous, by the way). If I drop
it into the docking station, it kernel panics, often within five
minutes. The entire machine will be frozen, with just the Caps Lock
light flashing at me.
Yesterday I powered up the machine in the dock and walked away for ten
minutes. When I came back I discovered the kernel had panicked--and I
hadn't even logged in yet.
I figured the most likely culprit was driving the 30" Dell widescreen
monitor hooked up to the docking station. The laptop doesn't have its
own DVI port, so I can only drive the monitor at 2560x1600 with the DVI
port on the docking station. I'm using the NVidia 177 (beta) binary
driver (nvidia-glx-177).
However! I've also experienced some kernel panics even when not using
the docking station. The minimal configuration that panicked the kernel
had a USB hub with a USB mouse and keyboard attached; it didn't happen
nearly as soon as when using the docking station, it panicked maybe an
hour or two after booting. I disconnected the USB hub, hard reset, and
the machine ran all day.
The only unconventional things about this install:
1) The root partition is encrypted (I used the alternate installer).
2) The home partition is encrypted, and formatted with ZFS. It's automatically
mounted during startup with an Upstart script I wrote.
I can't imagine those are related to the panic, but I've been wrong before.
I'm *very* interested in solving this problem, but I'm only marginally
competent at Linux. To start with, I have no idea how to find any error
message associated with the kernel panic. Please--how do I find out why
the kernel panicked?
