Subject: gentoo-2.6.15-r1 - Kernel oops when removing then reinstalling DVD drive into Pismo mediabay
Date: Fri, 12 May 2006 21:09:37 -0400 [thread overview]
Message-ID: <20060512210937.70edf87b@zetagundam> (raw)
This is using the 2.6.15 kernel with the Gentoo patches. The 2.6.16
kernel also exhibits this behavior.

Basically, what happens is that if I pull the drive and then reinsert
it (doesn't matter how long) it immediately does this and the keyboard
seizes up. If I ssh in and kill the process that was on that console,
the kernel will continue to run, if I recall correctly. (Of course,
being a laptop, this is rather impractical most of the time.) Usually
when this happens, the drive is *not* mounted at all.
