I will pull the cpu model number for you, but every 2+ ghz p4 I
had tried, hyperthreading required being disabled to make the machine run.
Not sure why. Is it related ???

Yeah and the system is perfectly fine running on 1 core when
doing heavy lifting.

could take a picture or get it from the boot loader (cf. https://dev

you need to enter KDL manually first to have a chance of it working on a
later panic.

I got the syslogs in the ticket now. If those aren't enlightening
I will take photos of the kdl tonight, though there seems to be little
consistency outside of fialures of the vesa driver. I also get frequent
fialures on building due to lost or unfound files when building. Maybe
those 2 problems are related ? Anyways to test disk and ram caching for
bugs besides KDL ?
> As written before, the most interesting information would be to
determine whether this is a Haiku regression or not. So, please test an
older version to verify that. If it is a Haiku regression, tracking down
the exact revision (or at least a narrow range) that caused the issue via
bisection would be very helpful. While that may take some time, it will
probably take less time on both ends than trying to analyze the issue,
particularly when KDL remains unaccessible to you.

I will try to test it down to a range, but I have always had some
stability issues with haiku when building.
> PS: In Wiki syntax spaces at the beginning of a paragraph indent it.
Horrific typist here, please exscuse, will try to be more cognative of
this in the future. is this a IE problem becuase I see a indent in my
editing windows but not in the ticket itself ?
