I'd be glad to post a PR and assist in helping to get it permanently
fixed. I certainly don't want this data to get lost and honestly our
business uses FreeBSD on VMWare so much that we really need a permanent
fix as much as anyone else :-)
The reason I've hesitated to post a PR so far is that I didn't have any
truly useful or concrete evidence of where the problem lies. After Dane
Foster contacted me and told me he could recreate the crash on demand with
his workload it was easier to narrow things down. The suggestion that it
was an interrupts issue (by possibly Bjoern Zeeb?) and Dane's discovery
that his crashes ceased when em0 and mpt0 share an IRQ, but em0 is
completely unused was starting to prove there is some strong evidence here
in favor of the interrupts issue.
Dane, what's the status on your end? Has your fix still been successful?
Is it also stable if you simply set hint.mpt.0.msi_enable="1" ?
