Subject: b43 bug on card removal
Date: Tue, 22 Jan 2008 18:59:02 -0800 [thread overview]
Message-ID: <4796AD76.7020304@candelatech.com> (raw)
I cloned wireless-2.6 and am using the 'everything' branch.
I have some other networking patches applied as well, but nothing
directly wireless related.
I updated git earlier today and booted it up on a laptop with
a built-in ath5k and a cardbus b43 NIC.
Looks like I still need to get firmware installed...not sure if that
causes the next oops or not.
I just pulled git again, and tried the removal with the new kernel.
The panic is different this time (see second set of traces below)
