 |
|
I have Q6600 on the Gigabyte's GA-P35-DS3R ver2.1 (latest F13 BIOS) running gentoo-sources-3.0.6
during the last boot only one core was recognized:
| Code: | ...
CPU0: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz stepping 0b
Performance Events: PEBS fmt0+, Core2 events, Intel PMU driver.
PEBS disabled due to CPU errata.
...
Booting Node 0, Processors #1
smpboot cpu 1: start_ip = 9b000
CPU1: Not responding.
#2
smpboot cpu 2: start_ip = 9b000
CPU2: Not responding.
#3 Ok.
smpboot cpu 3: start_ip = 9b000
CPU3: Not responding.
Brought up 1 CPUs
Total of 1 processors activated (4799.99 BogoMIPS).
... |
but later:
| Code: | ...
microcode: no support for this CPU vendor
Kernel panic - not syncing: CPU#3 already initialized!

any info on how to get system to start with all 4 cores each time ?

notice this: | Quote: | | no support for this CPU vendor |
boot sysrescd, see if all cpus are there, is so, chroot into your gentoo, grab one od puppy mcfee's kernel seeds an reconfigure your kernel.
if you see the same issue in sysrescd, time to shop for a new cpu/mb/computer.

Or your cpu is dead because i've seen you overclock high a corei7 cpu in another post, that's not bad, but seeing your cores are running at 70-75° is not something intel cpu are used too.
So did you beat your poor cpu to death ? |

this is a q6600, not a i7...

| I've seen this happen to my Phenom II after a rough reboot, usually power cycling the box fixes it. |

@Q6600
that's the CPU in the office storage box - a lot of hard drives, software RAID, one hardware RAID controller, 8GB of RAM for caches/buffers, NFS server and iSCSI target. never been overclocked, never will be - there's no need for something like that. so, I guess that CPU is safe and sound. if there's some hardware problem, I think it will be motherboard related, as that mobo is 3.5 years old. it should be quite long lasting having dry caps, but you never now with contemporary mobos...
power cycle solved the problem for now, but I don't like the idea having the possibility of running in such a problem on stock settings.
@i7
it's i5-2500k. here are specs:
http://ark.intel.com/products/52210
notice that max temp (72.6C) is the case temp.
temps in my post are core temps.
core temps should not go over 98C for this particular CPU.
by intel's specs all fans should be set to the maximum revs at the 80C to avoid climbing to >90C:
| Code: | cat /sys/class/hwmon/hwmon0/device/temp2_label
Core 0
cat /sys/class/hwmon/hwmon0/device/temp2_max
80000
cat /sys/class/hwmon/hwmon0/device/temp2_crit
98000 |
temperatures ~75C are achieved by 4 thread prime95 run to show max turbo frequency (that topic was about turbo freqs).
CPU is cooled by TRUE 120
http://techgage.com/viewimg/?img=/articles/cooling/cpu_cooling_roundup/cpu_cooling_roundup_0608_19.jpg&desc=CPU%20Cooler%20Roundup%20-%20June%202008
and fancontrol is set to give full throttle to CPU fan at 80C, just like official specs request.
without prime95, fan idles at ~400rpm giving these temps:
| Code: | Core 0: +38.0 C (high = +80.0 C, crit = +98.0 C)
Core 1: +40.0 C (high = +80.0 C, crit = +98.0 C)
Core 2: +37.0 C (high = +80.0 C, crit = +98.0 C)
Core 3: +37.0 C (high = +80.0 C, crit = +98.0 C) |
anyways, besides temps within the specs, this CPU was even overclocked without any voltage increase, so I guess it's completely safe, too.

recent AMD CPUs have quite low temp tolerance.
some of them should be kept under 63C, similar to famous Pentium III 1.13GHz...

Full dmesg: http://pastebin.com/uAkWhNhf
CPU: i5-2500k
Mainboard: H67MA-USB3-B3 with the latest bios
Tested kernels: 3.3.4-gentoo-sources / 3.3.4-vanilla-sources
interesting is: if i press some random keys at kernel boot, the kernel brought all 4 cores up. if i do nothing, the kernel brought up 1 core, 2 cores but never all 4 cores. comprehensible at every boot
/edit
also wondering about
[ 0.123225] PEBS disabled due to CPU errata.
"PEBS" is the same pebs, like "cat /proc/cpuinfo | grep pebs", or?!
regards
Kernel: 3.3.4 |

there is a errata in the i5 and i7 (I've seen the same output as I have i7-2600), but I do use all cores, try a reboot and see if it is reoccurring.

I remember last year AMD CPUs had similar troubles, which were solved
by deactivating C1E support in the BIOS.
Try to disable all PM-related features in the BIOS first. |

| Yep, I have one with the C1E bug. The problem is something to do with it shutting down when there's no external interrupts to process, whether or not there's other work to do. Combine that with things like CONFIG_NOHZ and you get a system that appears frozen until you move the mouse or type. |

hi,
.config -> http://pastebin.com/ePrmbaZ4
don't have this problem with current sysrescuecd. no luck with disabling C1E or other powersave relating stuff in the bios. no luck with unset CONFIG_NO_HZ. i'll trying 3.0.30 kernel now.
/edit
no luck with 3.0.30. getting a sysrescuecd dmesg now...http://pastebin.com/H9qQYPJB

try a -git kernel, and if that doesn't work either, report this to the
linux kernel mailinglist (along with last working kernel version, e.g. of the sysrescue cd). |

I have the same errata msg in my dmesg but all cpus are up, I'll paste bin my .config later on as I didn't noticed something strange about your.
