https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=247544 Bug ID: 247544 Summary: zvol: unbootable system with root on zfs [regression] Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: contact@evilham.com I have bisected the source (took me a few days, wanted to report with more info) and traced my issue down to revisions 362048 and 362047, coming from differential: https://reviews.freebsd.org/D23478 Running HEAD the two afore mentioned revisions reverted results in a properly working system. What I am experiencing with the mentioned revisions applied is a hanging boot sequence with following message (modulo typos because it's a transcript): /etc/rc: DEBUG: checkyesno: zfs_enable is set to YES. /etc/rc: DEBUG: load_kld: zfs kernel module already loaded. /etc/rc: DEBUG: run_rc_command: doit: zvol_start (no further messages are shown) The setup itself is somewhat standard: Created with the installer geli full disk encryption + zfs on root using the whole disk (with partitions for EFI, boot, swap as created by the installer). Inside the main pool, which contains the root dataset, I do have a zvol which in turn is also encrypted with geli and I only unlock when necessary. Hardware wise: this is a Lenovo A485 laptop with an AMD Ryzen processor (BIOS being up to date) and the disk is nvme using the nda driver (as opposed to nvd). I'll try to re-create this with a simpler setup that isn't my work one, but since this is scheduled to be MFC'd, I thought I'd notify this with as much information as I could first.
