Hi Dave,

okay, that's the 3rd report of this in the last months now and seems to be a
clean version of https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277432
then without other prior effect (or did you have a FW crash or similar
right before that which we don't see)?

Note the fix for  PR 275255 is NOT in 14 yet (and not in 14.1-R*).
I am just checking as to my memory you have an 8xxx (if that's the
same device)?   You'll want to apply 5a4d24610fc6 as well and if it
solves the other issues then that would very much help.  I only got
1 feedback on that so far.   (Sorry for mixing the two now)

Thanks!  I'll try o have a look at the core file unless yo uhave the
