https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290735 --- Comment #7 from Roman Bogorodskiy <novel@FreeBSD.org> --- Updated the box I was checking on to 15.0-RELEASE-p2 releng/15.0-n281005-5fb0f8e9e61d. Using almost the same testing scenario with the Ubuntu guest and VNC. The only difference is adding "-l com1,stdio" to get some more info on what's happening inside the guest. What happens: - Suspend works fine - Resume partially works: right after resume I can run commands in the serial console. Same symptoms with VNC: just frozen screen as it was during suspend. In a couple of minutes serial console gets unsable, I can see kernel messages like: [ 558.130566] INFO: task jbd2/vda2-8:301 blocked for more than 245 seconds. Assume the disk device hangs. Similar result with ahci-hd instead of virtio-blk, only different error messages by the kernel: 2026-01-30T19:07:50.448333+01:00 novel-BHYVE kernel: ata1.00: status: { DRDY } 2026-01-30T19:07:50.448342+01:00 novel-BHYVE kernel: ata1.00: failed command: WRITE FPDMA QUEUED 2026-01-30T19:07:50.451058+01:00 novel-BHYVE kernel: ata1.00: cmd 61/08:78:d0:5b:22/00:00:00:00:00/40 tag 15 ncq dma 4096 out 2026-01-30T19:07:50.451064+01:00 novel-BHYVE kernel: res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x56 (ATA bus error) 2026-01-30T19:07:50.451064+01:00 novel-BHYVE kernel: ata1.00: status: { DRDY } [ 287.665686] ahci 0000:00:07.0: AHCI controller unavailable! Same thing happens without VNC, i.e. without the " -s 5:0,fbuf,tcp=127.0.0.1:5957 " chunk. Looks like there's a regression between 14.3 and 15.0. Unfortunately I do not have bootenvironments/zfs, so cannot bisect to a specific commit. -- You are receiving this mail because: You are the assignee for the bug.home | help
