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 select= ing the various options from the loader menu: * No serial console, no verbose =3D hang * Serial console, no verbose =3D boots * No serial console, verbose =3D boots * serial console, verbose =3D 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-RELEAS= E to 14.1-RELEASE, but I thought it was i915 related. I set (and kept) verbose b= oot 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
