Hello same problem here on DELL PowerEdge R210.
Starting with OpenBSD 4.8 Release was Ok. Applying patchs one by one until patch 006_cbc.patch System cold reboots with this patch. Back to kernel GENERIC.MP 4.8 release + patchs : 001_bgpd.patch, 002_pci.patch, 003_vr.patch, 004_openssl.patch 005_pf.patch, is Ok. 2011/3/24 Kapetanakis Giannis <bil...@edu.physics.uoc.gr> > > I've tested a while ago the GENERIC.MP kernel of 4.8-stable and the system > cold reboots.
