Their boot environments were created as described in comment #0. The results were as follows: - 10.3-RELEASE: works - 10.3-STABLE: works - 11.0-RELEASE: works - 11.1-RELEASE: broken as described in comment #0 - 11.1-STABLE: broken as described in comment #0 - 12.0-CURRENT: works In order to pinpoint the breakage I checked the revisions between 11.0 and = 11.1 in a way similar to git-bisect (binary search). So after compiling a few kernels and rebooting several times I found base r318197 to introduce the breakage. Revisions before that are able to mount my root filesystem just fine. But revisions after (and including) base r318197 result in "Mounting from zfs:ssd/ROOT/(...) failed with error 6." during boot. I don't know anything about hardware or kernel development, so I'm just speculating here: base r318197 only touches MMC and SD stuff, so I'm not su= re how that could break assembling my ZFS pool, which is located on SATA disks= .=20 But the notebook does have a SD card reader... Also base r318197 mentions = that a few commit were only partially applied. Maybe something went wrong when backporting them, which would explain why 12.0-CURRENT works, but 11.1 does= n't. I hope this is helpful in pinpointing the cause. --=20 You are receiving this mail because: You are the assignee for the bug.=
