FC6 Keeps Crashing, cant find problem

[Byroman]

Humm... I cant seem to find a configuration file for the kernel. Theres a config-2.6.18-1.2798.fc6, but thats for the other kernel.
Heres what files are in the /boot directory:

[root@localhost boot]# ls
config-2.6.18-1.2798.fc6 System.map-2.6.18-1.2798.fc6
config-2.6.18-1.2798.fc6~ System.map-2.6.19-prep
grub System.map-2.6.19-prep.old
initrd-2.6.18-1.2798.fc6.img vmlinuz
initrd-2.6.19-prep.img vmlinuz-2.6.18-1.2798.fc6
lost+found vmlinuz-2.6.19-prep
symvers-2.6.18-1.2798.fc6.gz vmlinuz-2.6.19-prep.old
System.map

Hope this exists on ur system

[root@localhost linux-2.6.19.i686]#

Go thr and do

[root@localhost linux-2.6.19.i686]# cat .config

in that, u shud find a section like this

#
# Multi-device support (RAID and LVM)
#

From that line, copy till the last CONFIG_DM_******=* option.

Can you paste that here?

[Byroman]

Ok, here it is:

#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
CONFIG_MD_LINEAR=m
CONFIG_MD_RAID0=m
CONFIG_MD_RAID1=m
CONFIG_MD_RAID10=m
CONFIG_MD_RAID456=m
CONFIG_MD_RAID5_RESHAPE=y
CONFIG_MD_MULTIPATH=m
CONFIG_MD_FAULTY=m
CONFIG_BLK_DEV_DM=m
CONFIG_DM_DEBUG=y
CONFIG_DM_CRYPT=m
CONFIG_DM_SNAPSHOT=m
CONFIG_DM_MIRROR=m
CONFIG_DM_ZERO=m
CONFIG_DM_MULTIPATH=m
CONFIG_DM_MULTIPATH_EMC=m

Hope this helps

[cyberinstru]

Ok. Now, change the config options as follows:

CONFIG_BLK_DEV_DM=y
CONFIG_DM_DEBUG=y
CONFIG_DM_CRYPT=y
CONFIG_DM_SNAPSHOT=y
CONFIG_DM_MIRROR=y
CONFIG_DM_ZERO=y
CONFIG_DM_MULTIPATH=y
CONFIG_DM_MULTIPATH_EMC=y

Save it and do
1. Delete the old initrd file "initrd-2.6.19-prep.img" from /boot directory
2. make all
3. make modules_install
4. make install

Now reboot and it shud be fine.

Gud luk

[Byroman]

Thanks a lot! It booted fine. I will now leave it over night and see how it lasts...

[cyberinstru]

Gr8! Also track for abnormal logs.. it wud be useful if it freezes again

[Byroman]

Dang... nope unforutnatly this morning when I checked the machine, it had crashed. According to host-tracker.com it crashed right around midnight. My logs show that at 12:11 there was a hole wack of error messages, most of which I dont understand, so maybe this could lead us to the problem. Take a look at the new messages log here. I cant seem to find anything else abnormal in the other logs.
Can you make sense of this log?
Thanks a lot!

Hey,
From the logs, i doubt if u have really disabled SMP or not. Like u did before, can u open '.config' file, search for

CONFIG_SMP

and paste that line here.

The line should be like this:

# CONFIG_SMP is not set

. It means, it is disabled.

Also do u really need SELinux? If not, u can also disable that. Disabling SELinux doesn't require kernel re-building

Ok, heres the section "Processor type and features" from the .config file:

SMP is dissabled, does the rest of the configuration look alright to you?
No, i guess I really done need selinux, ive dissabled it and will see how that goes.
Thanks for all the help

[Byroman]

Well, i guess selinux didnt help, it still crashed.
One other thing- this morning when I restarted it, I didnt notice that apache gave me some error when it was booting, and didnt start correctly. When I got home today, the machine was running alright. But then mater on when I tried to acess my website, it didnt load, so of course i checked the server, and sure enough apache wasnt started. Could apache be causing me all this trouble?! im using the newest version i beleive.
Thanks
