Refer to the 2nd bullet point here: > https://www.freebsd.org/releases/10.2R/errata.html#open-issues Thank you very much for this pointer! I only read the announcements in the release notes, not the errata... > As described in /usr/src/UPDATING entry 20121223, rebuilding the kernel > with options KSTACK_PAGES=4 has been observed to resolve the boot-time > crash." I sincerly hope this solves my issue. I'll report back when I've compiled the kernel. That's going to take a while... my (slow!) Atom CPU has been compiling the kernel-toolchain for the last six hours, and still going.... Hopefully I can start compiling the kernel tonight... Perhaps it time to learn how to compile a i386 kernel for my slow Soekris on my (faster) amd64 server. :) Thanks again for the pointers! Freek
