Synopsis: FreeBSD 6.2 Stable Kernel Update Prevents Dell PowerEdge 1750 (SMP) From Booting State-Changed-From-To: open->feedback State-Changed-By: rwatson State-Changed-When: Fri Feb 23 15:20:27 UTC 2007 State-Changed-Why: Is the problem described in this PR and your smp@ posting the same as the one described in PR 103697? http://www.freebsd.org/cgi/query-pr.cgi?pr=103697 Could you confirm whether you are using the ULE scheduler or not? 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... http://www.freebsd.org/cgi/query-pr.cgi?pr=109267
