I have done everyday work on my ZFS-enabled FreeBSD7 box. It is having
4*250G disks in a RAIDZ array (the base system is on a separate disk).

Of course I have tried the things described at [1] but they did not
work, same crash occured when importing. Haven't yet tried OpenSolaris,
though.
I can provide the dump should it be needed.
TIA for looking into the issue.
Silly me, forgot the [1] URL: http://tinyurl.com/2ytg3w

I don't want to scare you, I loose my data from the zfs filesystem in the thread pointed by you... After some days of tries to repair this with Pawel (and his contact @zfs-discuss), I ended recreating the filesystem and assuming the lost of my data. This was the first of two times that I lost the same pool with zfs, after the second time I had to give up from zfs because my job will not resists to a thrid time..... Maybe Pawel can help you... Regards, Alexandre
Some updates on this... 'zpool import' shows the pool OK but when I try to actually import it, I get the aforementioned panic. Under BeleniX I cannot import it because it says the pool is corrupted. The (crash) problem also occurs with 7.0 beta 2. So I cannot access an otherwise healthy pool now. :-P Now I got to examine the logs too. Right before the pool becoming unaccessible, these log entries appeared: Jan 20 17:12:01 ginger kernel: vm_fault: pager read error, pid 1282 (rtorrent) Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad14 offset=23070008320 size=44032 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad12 offset=23070008320 size=44032 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad8 offset=23070008832 size=43520 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad10 offset=23070008832 size=43520 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad14 offset=23070008320 size=44032 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad12 offset=23070008320 size=44032 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad8 offset=23070008832 size=43520 Jan 20 17:12:01 ginger root: ZFS: checksum mismatch, zpool=tank path=/dev/ad10 offset=23070008832 size=43520 Jan 20 17:12:01 ginger root: ZFS: zpool I/O failure, zpool=tank error=86
