Dear kernel maintainers,

There is a known bug[1] in the linux kernel which causes some laptops
(for example the HP Compaq 615) to freeze during boot (screen turns
black, machine doesn't react on anything). The problem has been located
in the b43/ssb driver and has been fixed[2] some time ago.

As a workaround, one can use the proprietary wifi driver[3] (I'm doing
so on my HP Compaq 615) or start the kernel with "nolapic" and/or
"acpi=off" (disables wifi completely, but also SMP).

The people currently seeing this bug include myself and
"k k <kader25@gmail.com>", who has recently filed this bug report
against firmware-b43-installer and who was able to confirm[4] that the
latest linux kernel from experimental fixes the problem.

It would be great if the upstream patch could be backported and included
in the squeeze kernel! If you'd like, I can test the patched version

Many thanks for your work and with best regards

Alexander Kurtz
