https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285867 --- Comment #31 from Anthony Williams <anthony@adfw.co.uk> --- (In reply to Mark Millard from comment #28) top on 14.1 says 2 CPUS. A bit of another piece to the puzzle, however! Booting up the 14.1-R memstick to gather the top data, I found it hung on boot... >From a sample of several reboots, I found that with SMP enabled, and selecting the various options from the loader menu: * No serial console, no verbose = hang * Serial console, no verbose = boots * No serial console, verbose = boots * serial console, verbose = boots So there seems to be a variant of this issue in 14.1-RELEASE as well. Could a possibility that either verbose or serial console boot options slows the boot process down enough to escape whatever is causing the lockup? I now recall something like this happening when I upgraded from 14.0-RELEASE to 14.1-RELEASE, but I thought it was i915 related. I set (and kept) verbose boot in loader.conf when diagnosing it back then, and that seems to have been sufficient to boot 14.1-RELEASE reliably, but it's not "good enough" for 14.2. -- You are receiving this mail because: You are the assignee for the bug.home | help
