Booting with -s should make no difference (since booting fails during a very early initialization stage). I tried -v, but found that I could not reproduce the cold boot problem without the system being at least in S5 for hours (just switching off power and waiting a few minutes did not suffice, but this morning the system again booted only on the first attempt). This behavior obviously limits the rate of tests possible ... It looks as if the memory holding the loaded kernel and/or modules is corrupted before the kernel is reloaded and started, as indicated by this morning's boot failure: kldload: unexpected relocation type 268435457 kldload: unexpected relocation type 67108865 Fatal trap 12: ... The rest of the panic message and back trace is identical to the trap 12 panic details in my previous message. It really looks as if the loaded kernel image is corrupted at random positions, leading to random panics (but often of the type trap 12 or page fault in kernel) when execution reaches damaged code or data. A reboot succeeded without any problem as in all prior cases ... Any ideas? Regards, STefanReceived on Fri Nov 11 2011 - 11:11:20 UTC
