First problem I notice is a panic, which seems to occur every time 'tar' is used. Might be unrelated to tar, but it definately provokes it. Simply the tar command or a pkg_add causes it. Sorry I don't have a serial console, but here's a picture of the screen: http://www.rootshell.be/~msp/IMG_4002.JPG I initially had a zfsbooting root, from a CF, plus a RAIDZ2 on HDD. Everytime I tried to perform a pkg_add I would get this panic. I then moved root to ufs and the pkg_add would then not cause the panic. However, any tar which accessed the zfs raidz2 pool still causes this panic. Is this known? I couldn't see the same reported anywhere, so forgive me if I have missed it. Please let me know if you need kernel config, etc. to debug this further.
