>Synopsis: panic: kernel diagnostic assertion "pg != NULL" failed: file
>"/usr/src/sys/kern/vfs_biomem.c", line 308
>Category: kernel
>Environment:
System : OpenBSD 6.6
Details : OpenBSD 6.6-current (GENERIC.MP) #493: Wed Nov 27
22:27:15 MST 2019
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I got the same panic within a span of several minutes:
panic: kernel diagnostic assertion "pg != NULL" failed: file
"/usr/src/sys/kern/vfs_biomem.c", line 308
The rest of the panic information can be found here:
https://photos.app.goo.gl/B9YRZ6dgJrchY9AH7
The USB keyboard doesn't work in ddb(4) and I can't get
backtrace I'm afraid.
It is most likely related to the recent commit:
