But. . . Looks like I Parse the 067613.html report differently than you do: A) First it says: Most recent CURRENT, as with r326363, crashes on booting the kernel This is different than it later reports about -r326347 as I parse the statements. B) Then it says=20 The last known half-ways good kernel is 12.0-CURRENT #157 r326347 Note the "half-ways" part. It then continues with what I interpreted as a description of "half-ways" in a booted -r326347 context (so, not for -r326363). When performing buildworld/buildkernel/relaese/package or poudriere on a ZFS filesystem, I can now bring down the system almost in a reproducible way. I could be wrong but I do not see that as a report of the "the last known good kernel". --=20 You are receiving this mail because: You are the assignee for the bug.=
