Unfortunately fixing this issue by installing zfsboot from 9.0-BETA2 was a surprising amount of work, because of an incompatibility between the 9.0 USB installer GPT and the BIOS on this system. It took quite a while to recognize the root cause for that one. I simply cannot boot the system in question with the GPT pmbr used on the memstick of 9.0. The BIOS locks completely. I am very reluctant to risk breaking my currently running system, the previous boot failure caused almost two weeks of downtime. Does the 8.2-stable memstick image still use MBR? If so, I could conceivably try to copy the 9.0 zfsboot version to the 8.2-stable memstick and test both. Regards, Camillo
