Hi!
I can see X redraw the screen top down very slowly when I use the SMP
kernel on my Thinkpad T60. I can actually see it draw the background
first and then every widget one by one. I don't see this behaviour when
I use GENERIC.
I use an the amd64 kernel.
I tried with a 2 month old snapshot and a freshly built GENERIC.MP
checked out this afternoon with the same result.

spaceman% uname -a
OpenBSD spaceman.my.domain 4.2 GENERIC.MP#0 amd64

dmesg: http://www.hcl-club.lu/~jaj/foo/dmesg
`X -version`: http://www.hcl-club.lu/~jaj/foo/xversion

Is this a know issue?
Do I need to rebuild Xenocara with special knobs to use it with bsd.mp?
Could you point me into a direction to further investigate this?

Best regards,
Jona
