Hi

I've recently installed OpenBSD 4.7 Release on my laptop, an Acer Aspire 
One with SSD. Enjoying the improved performance I decided I wanted to 
follow current. I was hoping for webcam and ath0 support. (Apparently 
I'm SOL when it comes to the ath0, its one of 'those' chipsets that 
doesn't work)
The major problem I have is that on current (snapshot or compiled latest 
source) X stops working.
In release everything works fine, run gnome, got nice visual effects, 
everything seems fine.
In current (snapshot June 7th) when X tries to start the LCD panel turns 
off completely (not just goes dark) actually goes black like it does 
when the computer powers down.
I'm happy to substitute the ath0 with my ural or rum but I can't live 
without X working.
Attached is -release and -current dmesg along with pcidump -v

Regards
Dusty

Hi

I also crash X server. My graphics controller is an Intel GMA 3150 tested
with OpenBSD 4.7.

I haven't crashed the X server per say. Its working brilliantly on 
-release. On -current X appears to load but the LCD panel powers off. I 
can CTL+ALT+F1 and blindly log in and reboot, so the system is still 
responsive.
I've tried this with both -release and -current bsd.mp as well as 
-release and -current bsd with the same result.

Can you provide Xorg.log from both?

also can you confirm that the X snap was also the latest?

So far there isn't much informatino to go on.

can you ssh to the machine after the screen goes black and get
logs/dmesg from the machine then?
