Hello,

Saw this on one of my Linux machines with a Linux (community supported USB 
stick):

I'm dropping LKML from cc, no need to write there if there is a specialized
mailing list.

It looks like the bitmap code in carl9170 needs reviewing.  I spotted
one error immediately.  bitmap_zero() takes the number of bits, not the
number of long integers.

Chances are not very high that it would help in your case, but here's
the patch.  I hope to give carl9170 some good testing before submitting
that patch formally.

carl9170: fix bitmap initialization

From: Pavel Roskin <proski@gnu.org>

bitmap_zero() takes the number of bits, not the long integers used to
keep them.

Hi,

Patch applied to both hosts, rebooted and both running again, will let you
