Console output during failed boot
------- Comment From mkravetz.com 2012-09-06 20:39 EDT------- vanilla kernel fails in the same way as RT, so this may not be RT related. off to build/attempt to boot mainline. ------- Comment From mkravetz.com 2012-09-06 21:29 EDT------- 3.0.42 (unmodified) also fails to boot. Therefore, we can safely say this is NOT a RT issue. Sorry for the noise Red Hat MRG team ------- Comment From mkravetz.com 2012-09-06 21:52 EDT------- Just to verify, I restored uEFI settings to their defaults (F1 during system initialization). With setting back at the defaults, 3.0.42 kernel boots. ------- Comment From mkravetz.com 2012-09-07 23:36 EDT------- This e-mail thread appears to describe the issue: https://lkml.org/lkml/2011/12/14/102 ------- Comment From mkravetz.com 2012-09-08 00:58 EDT------- Changed the UEFI setting "ProcessorXapic" to disabled and the MRG 2.1 kernel boots. So, the question is should CONFIG_X86_X2APIC be enabled in the MRG 2.1 kernel(s) ? ------- Comment From mkravetz.com 2012-09-11 22:46 EDT------- Just checked and 2.2 candidate kernel (i have access to) does have CONFIG_X86_X2APIC enabled. I'd prefer not to change the MRG 2.1 configs as we're about to release MRG 2.2 (and that has X86_X2APIC enabled). |
