Daughter’s project complete!!!

zero out drive for good measure. reboot.... garbage on the serial console.... power cycle. garbage. power cycle.. garbage... vague memories that this is why I pulled one of these machines out and gave up on the series for anything real...

Now I begin my trek through my spares....

No point trying to recover, and it is old.. there's no way this data is valuable, I look at it again.. yeah.. toast it. download fresh 12.2-RELEASE-SPARC.disc1.iso, check chesksums and signatures (ALWAYS DO THIS).. now to find CDR media... ZOMG found some... ZOMG, cdrecord works.. boots.. errors on sector way at the end. whatever burn again.. slower speed. new disk fails the EXACT SAME sector. whatever.. just boot and go

Morning. power outage.. crap.. go to check, the tar finished, great.. system reset, sitting at fsck.. unexpected fileystem error.. crap. run fsck ... EVERYTHING is corrupt.. double crap.. vague memory that I knew this.. that for some reason fsck on 11 on sparc would flag everything as bad even though filesystem was consistent, but fsck on 10 would show it all as good... crap...

ah, yes.. where did we leave off... oh yes.. it boots, it works.. wow even attempting the emulation was a waste of time. running FreeBSD 11.. so even pretty recent (for SPARC)... check it out.. 1G RAM.. but no swap. and there's some data on the drive I should preserve before I nuke it. Start the tar.. go to bed.

Relent. give up. Hardware time.
Go downstairs, find most convenient box pick it up, clean it off, bring it up, plug in, turn on.
WTF.. It boots. Its is sitting at a login prompt?! EVEN THE NVRAM IS VALID?!?!?!

IT BOOTS. yay..
wait.

interrupt storm detected on "vec2016:"; throttling interrupt source

after kernel takes over. search, find:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239068

Try recompiling as suggested, try turning off DMA on FreeBSD... try booting virtio.. sparc64 doesn't support virtio. try booting scsi, qemu doesn't support SCSI on sparc64 (non virtio)

wtf... search... search... search, find:
https://bugs.freebsd.org/bugzilla//show_bug.cgi?id=256536

Ok, implement the workaround (set environment variable.. .BUILD. Success. run...

Step one... compile... get the following error:

warning: POSIX Yacc does not support %define [

the build doesn't even exit cleanly.

my sparc64 hardware is OLD. *OOOOOLD*. ok, qemu has sparc64 support... lets do that, that will be easier than dealing with hardware...

Look at the data.. yup, its there, lets see what I can do.. this will be maddening to walk by hand.. screw it. sparc64 we go....
