I booted 2.6.32-5 with the debug option on, and for comparison did the same with 2.6.30-2. The errors concerning the power management itself are also showing up in 2.6.30-2. But whereas 2.6.32-5 afterwards crashes with a divide error, 2.6.30-2 starts up normally: Here the according section of the 2.6.30-2 protocol (if You would like to obtain the complete protocol, just tell me) : ======================================================== [ 0.692003] ERROR: groups don't span domain->span [ 0.696004] CPU3 attaching sched-domain: [ 0.700003] domain 0: span 2-3 level MC [ 0.708003] groups: 3 2 [ 0.720003] domain 1: span 1-3 level CPU [ 0.728003] groups: 2-3 1 [ 0.744003] domain 2: span 0-3 level NODE [ 0.752003] groups: 1-3 (__cpu_power = 2048) [ 0.766180] ERROR: domain->cpu_power not set [ 0.768003] [ 0.772003] ERROR: groups don't span domain->span [ 0.776172] net_namespace: 1936 bytes [ 0.780049] Booting paravirtualized kernel on bare hardware [ 0.784149] regulator: core version 0.5 [ 0.788114] NET: Registered protocol family 16 [ 0.792037] node 0 link 2: io port [0, 2fff] [ 0.796004] node 0 link 0: io port [3000, 3fff] [ 0.800004] TOM: 0000000080000000 aka 2048M [ 0.804004] node 0 link 2: mmio [d0000000, d04fffff] ============================================================= And here the complete protocol of the 2.6.32-5 crashing: ============================================================= bash-3.00$ tip hardwire connected [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 2.6.32-5-amd64 (Debian 2.6.32-27) (m...@debian.org) (gcc version 4 .3.5 (Debian 4.3.5-4) ) #1 SMP Sat Oct 30 14:18:21 UTC 2010 [ 0.000000] Command line: root=LABEL=S_rt ro debug console=ttyS0 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Centaur CentaurHauls [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: 0000000000000000 - 000000000009d400 (usable) [ 0.000000] BIOS-e820: 000000000009d400 - 00000000000a0000 (reserved) [ 0.000000] BIOS-e820: 00000000000ce000 - 0000000000100000 (reserved) [ 0.000000] BIOS-e820: 0000000000100000 - 000000007ff60000 (usable) [ 0.000000] BIOS-e820: 000000007ff60000 - 000000007ff72000 (ACPI data) [ 0.000000] BIOS-e820: 000000007ff72000 - 000000007ff80000 (ACPI NVS) [ 0.000000] BIOS-e820: 000000007ff80000 - 0000000080000000 (reserved) [ 0.000000] BIOS-e820: 00000000fec00000 - 00000000fec00400 (reserved) [ 0.000000] BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved) [ 0.000000] BIOS-e820: 00000000fff80000 - 0000000100000000 (reserved) [ 0.000000] DMI present.
