I have been having these issues since before the ZFSv15 patch was committed to HEAD a few months ago. let me know if you need details, I have no problems giving you root ssh on this machine... but it does not have a serial port. so I am not sure how useful it would be. --=20 Sam Fourman Jr. Fourman Networks http://www.fourmannetworks.com
