Kernel Update To 6.2 Stable Causes Dell PowerEdge 1750 (SMP) To Freeze On Boot

[Sean Benoit]

Hello,

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...


Thanks in advance for any help,
