I'll look into this. It seems that this is the last post in this topic. I have an HP DL145G2 with 4 GB RAM (dual AMD64) and with two SATA disks, on which I created a mirror (gmirror). It dies with this in the moment I issue gmirror insert ad6 on a degraded mirror. Setting hw.physmem below 4G solves the issue. The interesting stuff is that the machine worked with 4G with earlier kernels (6.0-BETA5 I think). What has changed?
