Kernel panic with 4.99.64 kernel on an iBook SE

["David H. Gutteridge" <dhgutteridge%sympatico.ca@localhost>]

Hi all,

I thought I'd test the latest -current kernel, per Michael's request to
check things out in anticipation of the 5.0 branch.  A kernel from last
night's releng build panics on boot during disk activity, like so:

panic: sme_events_worker: invalid units for ENVSYS_FMONSTCHANGED
Stopped in pid 0.26 (system) at netbsd:cpu_Debugger+0x10:        lwz     r0, 
 r1,  0
x14
db> bt
0xd4c4ee10: at panic+0x21c
0xd4c4ee60: at sme_events_worker+0x230
0xd4c4ef10: at workqueue_worker+0xa0
0xd4c4ef40: at emptyidlespin+0x10
0xd4c4ef50: at 0xfffffffc

I can try building and booting a diagnostic kernel if this is an
unknown issue.

Regards,

Dave

PS dmesg is:
