It took a bit longer sorry but I have more infos now.
The acpi_pm was not related to that I still get the problem.
Of course I still can try to find the commit which magically fixed acpi_pm if you really want.
It seems like it breaks only when you enable HT and only on 2 socket motherboards.
( at least the ones I own , I know is old hardware but worked fine for me )
Also disabling the second CPU and enabling HT works , enabling both CPUs and disabling HT works ,
booting with enabled HT and both CPUs but maxcpus=2 also works , booting with 2 CPUs and HT on breaks ,
booting with both CPUs HT on but maxcpus=3 breaks also.
Also I have another dual motherboard here 604 socket with 2 2,4 GHz Xeon's.
The motherboard has the storage controller somewhat broken but for a quick test it is still good :) and I see the
same thing.
Does that make any sense ?
Also all that tested on 2.6.25-rc6-00224-gae51801-dirty ( dirty while I reverted the revert =) )
