how can porteus run while others crash

Post#1 by bour59 » 21 Jun 2014, 13:41

Hello
The story :
I get a PC with vista crashed (noway to reinstall other version of this os)
I recover datas using cd Porteus 3.0
then
repartition the whole disk 1T (3primary of 2G and one extended)
I install slackware 14/14.1 : ok, but crashed also when booting (cpu-tod problem)
I install porteus 3.O : ok works fine in text or X (razorqt)
I don't understand why Porteus can run and others don't
Any idea !
Porteus 3.0 is wonderful

My guess is a corrupt hard drive. Porteus only uses the first ~300MB and loads itself into ram.

So an MCE occurs when the cpu detects a problem with hardware. I would run a memory check bootdisk, thena cpu check bootdisk. It could be another component on the mother board but these would be the first two places to look. That Porteus runs could be an indication that the slackware kernel does not like some piece of hardware. Try running slackware with the updated kernel.

Do these crashes occur when the machine is first turned on or after it has run for awhile. If the latter the problem could be heat related.

i'm fairly sure that MCE protection is compiled into Porteus kernel but please double check this.
please activate development module and run following command:
grep -i X86_MCE /usr/src/linux/Porteus*/kernel_config
(path and config name may be little different - can't remember right now)
Please add [Solved] to your thread title if the solution was found.

@fanthom

Code: Select all

grep -i X86_MCE /usr/src/linux/Porteus-patches/kernel.config

CONFIG_X86_MCE=y
CONFIG_X86_MCE_INTEL=y
CONFIG_X86_MCE_AMD=y
CONFIG_X86_MCE_THRESHOLD=y
# CONFIG_X86_MCE_INJECT is not set
@brokenmap
will try memtest86+ if I can create the module or the iso
Edit : memtest86+ complete with no error
@Ed_p
crash first boot after install

thx all
