reassign 604472 linux-2.6 retitle 604472 b43/ssb driver causes some laptops to freeze during boot severity 604472 serious tags 604472 patch upstream fixed-upstream forwarded 604472 https://bugzilla.kernel.org/show_bug.cgi?id=14716 thanks 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 first. Many thanks for your work and with best regards Alexander Kurtz [1] https://bugzilla.kernel.org/show_bug.cgi?id=14716 [2] http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.35.y.git;a=commit;h=9d1ac34ec3a67713308ae0883c3359c557f14d17 [3] http://packages.debian.org/squeeze/broadcom-sta-source [4] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604472#20
