Getting all boot messages in a file

[p1c0]

Hi all,

i'm new on this forum and i hope you will help me

I'va got two boxes: an old box where my LFS system works and a new one where i can't get it boot. My problem is the following. When my system is booting on the new box, it prints a lot of message on my screen and i can't read them since it prints faster than i can read!

Messages look like : [<c0...>] function_name ...

but i can't read more than that and i can't find what is my problem just with that. So my question is: can i redirect all boot messages in a file ?

I'm using grub, here is my /etc/syslog.conf:

auth,authpriv.* -/var/log/auth.log
*.*;auth,authpriv.none -/var/log/sys.log
daemon.* -/var/log/daemon.log
kern.* -/var/log/kern.log
mail.* -/var/log/mail.log
user.* -/var/log/user.log
*.emerg *

but i don't have those message in the log file...
Do you have THE solution to my problem ?

Thanks a lot for your help!

Hi and Welcome !

did you check 'dmesg' ?

dmesg | less

[p1c0]

it seems that i have forgotten to say that system doesn't boot on the new machine. It begin to boot and keyboard works well to configure bios but when i have those messages, i can't use keyboard. I just can shutdown the box by the power button...

[devils casper]

toggle 'Legacy USB support' in BIOS. keyboard will work after that.

[p1c0]

i have check in the kernel and usb keyboard is enable.

i have seen something like "do_page_fault" in the error message, perhaps a "disable" and a "clear" but i can't see more than that.

[devils casper]

could you post last visible error messages?

[p1c0]

no, i can't since i can't really read messages. I just have guess the mesage "do_page_fault".

I have recompiled my kernel without smp support and i have a kernel panic. There is an interrupt problem about apic. I don't know what is apic, i will search on google.

With smp support, it seems that it make a loop. There are always the same error messages.

[devils casper]

apic
pass noapic parameter to kernel. ( append kernel line with noapic in grub.conf ).

[p1c0]

it doesn't work

[p1c0]

here are some additional informations!

when i disable SMP (i don't need it) it doesn't boot and it finish on smp_apic_timer_interrupt

so i decided to disable APIC mode in my kernel configuration but i can't

i do make menuconfig and don't see options so i have edited the .config file and commented all lines with APIC but when typing make, it enable again the APIC options

do you have any solution ?
