System: NetBSD pismo 4.99.72 NetBSD 4.99.72 (GENERIC) #0: Tue Aug 26 03:58:07 EDT 2008 jmcneill@pismo:/usr/src/sys/arch/macppc/compile/GENERIC macppc
Architecture: powerpc
Machine: macppc
>Description:
	30 seconds after boot, cpu_tau_refresh causes a panic in sysmon_envsys
	on a PowerBook G3 (Firewire/Pismo) with the GENERIC kernel:

	panic: sme_events_worker: invalid units for ENVSYS_FMONSTCHANGED

>How-To-Repeat:
	Boot NetBSD -current on a PowerBook G3 (Firewire/Pismo).
>Fix:
	Workaround: comment out cpu_tau_setup/cpu_tau_refresh in
	src/sys/arch/powerpc/oea/cpu_subr.c

 This is effectively a duplicate of PR 38994.  (Though mine isn't as
 descriptively titled, nor does it offer the same workaround.)

 Log Message:
 Some fixes to the TAU support code:
 - set the ADC time according to clock speed, not some magic number
 - move some mtspr()s which we really only need to do once
 - make our envsys_data_t static, this should fix PR 39411
