[issue714] SMP kernel panic at boot: assertion: ((int)sr->sysid ..

[Thomas Nikolajsen]

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.
