Hi John, Thank you for your reply. The more I look the less confident I am that = this will in fact fix my wifi, but if it does it is just an added bonus= . I will submit a separate report to mobile@freebsd and focus on suspen= d/resume issues in this thread or at least a cleaner dmesg. The laptop suspends, but screen remains black and I need to hold down t= he power button to cut power. When restarting it just does a normal boo= t, suggesting unclean shutdown.=20 -----Original Message----- From: John Baldwin Sent: 03/02/2012 2:42:58 pm To: freebsd-acpi@freebsd.org Cc: Jakob Pedersen Subject: Re: ACPI error caused by broken asl, how to fix?

If your wifi card works at all (ge= ts interrupts, etc.), then worrying about ALKD is just a red herring. You might ask on mobile@FreeBSD.org about debugging your wifi issues. As far as suspend and resume, resume is not very easy to debug when it doesn't work. Does your screen come back at all if you resume or does = it just stay black? --=20 John Baldwin
