Re: controlfb and X

Hi all,

On   5 Nov, this message from Robert E Brose II echoed through cyberspace:

I'm now having the same problem with benh's dev tree. The really ugly
part is that there is no information on what happened nowehere: nothing
in X's log files, no oops in the syslog, no kernel panic on the serial
console... the kernel just seems to stop hard.

I've diffed benh's tree against Paul's latest copy I have (which doesn't
lockup with X), but without any clue so far. controlfb is identical
between the two....

I'll keep on investigating.

Cheers

Michel
