strange results. This bug has been in here for a loooong time.
Many thanks to Pedro Salenbauch for finding this.

regarding apm to LINT
- Disabled the statistics clock on machines which have an APM BIOS and
have the options "APM_BROKEN_STATCLOCK" enabled (which is default
in GENERIC now)
- move around some of the code in clock.c dealing with the rtc to make
it more obvios the effects of disabling the statistics clock

8 not the 18 I was using during some of my own testing. Ooops.
For those that want to change the number for experimentation, you can
set the value on line 1553 of this file.
One of the manifiestations of the problem includes the -4 RSS problem
in ps.

(Rev E or greater), aic7850, aic7860, aic7870, and aic7880 controllers.
SCB paging is enabled with the option "AHC_SCBPAGING_ENABLE". Full
comments on the algorithm are at the top of i386/scsi/aic7xxx.c.
options "AHC_TAGENABLE" and "AHC_QUEUE_FULL" have been removed. The
default is 4 tags without SCB paging, 8 with.
Clear the SCSIRSTI bit after throwing a bus reset. Some cards seem to get
confused otherwise.
Handle SCSIRSTI interrupts before checking to see if there is a valid
SCB in use since this can happen. (Clears PR# i386/1123)
Clean up the way we determine the number of SCBs on the card
(courtesy of Dan Eischen).
Guard against attempts to negotiate wide to a narrow controller.
Fix some comments.
Update my copyrights.
- More code cleanups
- #ifdef DEBUG debugging code
- More consistant printfs
- Better handling of the apm_int() assembly code (mostly from Bruce Evans)

common labels for LINT. There are still some common declarations for the
!KERNEL case in tcp_debug.h and spx_debug.h. trpt depends on the ones in
tcp_debug.h.
bug only affected FPU emulators. It might have caused bogus FPU states
in core dumps and in the child pcb after a fork. Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.
Cleaned up #includes.
Clarified GUS DMA Settings.
Other misc. changes.
This should hold us over until I can finish cleaning up TASD, and finish
reintegrating all of the FreeBSD changes to the sound driver. At that time
this document will be removed, and it's information moved to the handbook.
channel at the same time. The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.
Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed
