I have no clue about you Dell configuration nor the chipset.
However, I can say you my historic mini-pc (among others) has a chipset as well with shared memory *features*. It runs properly under any version of OpenBSD. The only time I experienced these "freees" moments is when I tried to overclock my motherboard over its limits from the Bios (over the limits of the cpu). Most probably your issue has this origin. Double check on the Intel website the spec for the limits of the CPU. Try to take down the amount of memory you allocated for the graphic side, as first, remaining on a nice default (doesn't seems X comes with very high requirements). Do every try one by one. Eventually copy on paper some data and load the defaults as last choice. Hope this help you, but again I don't think this is an OpenBSD issue. -- Daniele Bonini Stephen Harris <steveharri...@hotmail.com> wrote: > The symptoms of the freeze are similar to those described by i915kms > users, but the C400 laptop (1.2GH Pentium-M, 768M RAM) has the i830M > built-in graphics. > > This freeze also happens with NetBSD, FreeBSD, and several Linuxes. > It works, however, with OpenBSD 4.8 & 4.9. > > The commonality of current distros makes me think it is an X-windows > issue.
