:Thomas Nikolajsen <thomas.nikolajsen at mail.dk> added the comment:
:DDB trace uploaded in file .3; symbols weren't set up yet (early in boot),
:so I used 'nm -n' on kernel and added symbols to trace myself.
:perfmon popped up; after removing that from my KERNCONF problem isn't seen.
:For a solution we could just use MAXCPU rounded up to nearest power of 2,
:to add to gd_sysref_alloc to generate new sysid (instead of adding ncpus).
:It will give fewer sysids than current scheme with ncpus << MAXCPU,
:but MAXCPU has to be supported anyway.
This is easy. It's due to PERFMON trying to initialize its devices
way, way too early.
Fix coming up in a sec.
