SMP posting attached for reference to the PR:

> Last fall, while updating a 6.1 Stable kernel to 6.2 Pre-Release, I noted
> that the then new kernel caused all our previously functioning Dell
> PowerEdge 1750s (dual processor) to freeze on boot at the point in the
> boot process where the second processor was being detected. Disabling the
> second processor in the BIOS served as a temporary workaround and enabled
> the systems to boot successfully.
> 
> At that time I submitted a PR via the website and a patch was issued
> within a few hours. The patch resolved the problem. I didn't keep that
> original correspondence because I assumed that all was well moving
> forward.
> 
> Last weekend I attempted to update the same systems for the first time
> since last fall from the patched 6.2 Pre-Release kernel to the new 6.2
> Stable kernel. I was alarmed to see that the EXACT same issue had
> reappeared. The symptoms are exactly the same - as is the workaround
> (disable the second processor in the BIOS).
> 
> I have once again submitted a PR (109267) via the website (details at
> http://www.freebsd.org/cgi/query-pr.cgi?pr=109267); however, I have been
> advised that I should post the issue to this mailing list instead/prior.
> 
> Not sure what to do from here...
