Hi Mark,
Could you please submit bugs and CC freebsd-testing or another =
appropriate mailing list? It looks like there are some Arm64 =
architecture specific issues that need to be addressed based on the =
limited information I have from these emails.
Do you have DEADLKRES/INVARIANTS/WITNESS compiled into your =
kernel? If not, could you please do that?
If that doesn=E2=80=99t give any helpful hints, could you please =
panic the kernel and dump some debug info from ddb, e.g.,
1. alltrace
2. show allchains
3. show alllocks
Thank you,
-Enji
