>Description:
System panics with 'biodone: buffer not busy' randomly, but frequently
(e.g. attempting a full install seems to be a sure bet for meltdown).
Hardware configuration is summarized in boot output, above.
I have no previous history with FreeBSD on this hardware to offer for comparison.
I obtained a crash dump; I could FTP it to you if that would help.
