Joseph Fierro <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #19 from Joseph Fierro <[email protected]> --- Hello, We have done some additional testing on our end and this problem seems to be with virtio_random(4). We had a customer report a similar issue with FreeBSD 12.2 after enabling virtio_random with virtio_random_load="YES" in /boot/loader.conf. With 12.2, the system would intermittently hang after detaching all devices and reaching "rebooting...". In 12.2 this does not occur on every reboot--it seems to occur about 30% of the time. Removing that line from /boot/loader.conf resolved this problem. On a 13.0 RELEASE system in Vultr, issuing shutdown, reboot, or halt commands will cause the system to hang at "detaching uhub0" and the CPU ramps up to max. This happens on every reboot in 13.0, rather than intermittently (using the "-n" flag to skip the filesystem cache flush will actually avoid the problem, and the system will reboot without hanging). Simply manually unloading the virtio_random module with kldunload after boot is not sufficient to resolve the problem, as it will hang on reboot even after doing this. If the virtio_random module is never loaded in the first place, reboots, shutdowns, and halts will work properly. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
