On a server class ARM (Ampere) running an up to date stable/13 kernel with = INVARIANTS I get a panic in VFS code if I kldload linsysfs: pfs_add_node: homonymous siblings Anybody else see this recently? On a Raspberry Pi 3B with INVARIANTS the kldload works. There is a comment before the panic code /* XXX no locking! */ which makes me wonder if 32 cores is too many for this code. (Related to this: Does anybody get crash dumps on an Ampere system? If I c= onfigure DDB and use the debugger crash dump command it hangs after the 1% = progress line. Without the debugger the system just hangs without printing= any progress, but at least I can see the panic message before I power cycl= e it.)=
