Oh absolutely! :P I'm not the type to settle on a workaround.

I noticed that; but I couldn't find where it was indeed marked as bad.

Did you get my most recent email? (It was sent to your glommer[at]
address, and CC'd to the kernel list) If you didn't receive it, I'll
forward you the message. It included dmesg of good kernel, dmesg of
bad kernel, cpuinfo, .config, and my disassembled DSDT (which, as a
side project, I'm doing a full-blown reverse engineering of).

Thanks,

Andrew

P.S. I apologize in advance if this email is HTML, I'm at work and I
have to use the gmail web interface, I have it set to "text only", but
you never know.
