So far, the results are the following: 1) current Linus' tree doesn't boot with any command line (regression) [ Linus, please revert commit e66485d747505e9d960b864fc6c37f8b2afafaf0 x86-64: Disable local APIC timer use on AMD systems with C1E It's not necessary for 2.6.23 and actually kills the box that it's supposed to fix. ] 2) 2.6.23-rc8 w/ the "x86-64: Disable local APIC timer use on AMD systems with C1E" patch applied behaves like the current -git 3) 2.6.23-rc8 w/o this patch doesn't boot with either "noapictimer" _or_ "apicmaintimer" 4) 2.6.22 behaves like 2.6.23-rc8 5) 2.6.23-rc8 with (adjusted) patch-2.6.23-rc7-hrt1.patch boots only with "noapictimer" 6) 2.6.23-rc8 with (adjusted) patch-2.6.23-rc7-hrt1.patch and with the "x86-64: Disable local APIC timer use on AMD systems with C1E" patch boots without any extra command line options Tested for a couple of times with each kernel, the results seem to be reproducible 100% of the time.
