Hello, my sparc just finished doing a build release, with sources 
updated a few days ago, so it's now at at RC5. My machine is a SS5 with 
the TurboSparc upgrade, dmesg attached.

I have the options CFLAGS+=-mcpu=v8 -mtune=v8 -pipe and the same for 
COPTS set in mk.conf.

It seems that a kernel compiled with those options hangs; the last line 
printed is
"power0 at obio0 slot 0 offset 0x910000 level 2", the screen (17E20, 
attached to cgsix) flashes briefly, and then it just hangs.  no 
keyboard combos do anything, until I see the watchdog timer reset and 
I'm back at the OK prompt.

A kernel compiled without the options works seemingly fine - and all 
userland compiled with the v8 options is fine, too.  There seems just 
one teeensy bit of the kernel that doesn't like the -mcpu=v8 setting.

Anyone has seen this before?

Thanks,
Joe.
