[opensuse-kernel] Remote logging Kernel on a laptop
Hi, Because Kernel 2.6.34 crashes on my laptop while booting I want to do remote logging the boot process until the system crashes. Available ports: Crashing system (laptop with openSUSE): - USB - LPT - Bootloader: GRUB Remote systems (desktops with openSUSE): - USB - LPT - Serial Available cable: - USB/Serial (also possible connecting an adaptor Serial to LPT) Can you please say to me how I have to connect the cable (which port/plug to use on which system) and which commands I have to use on each system. (I know that the USB plug doesn't fit to the LPT port ;-) ) Thanks.

How far along in the boot process is it crashing? It may be that kdump is your best bet. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAkwVwQYACgkQLPWxlyuTD7JbxgCgmcogI26s0zKV4IwHXRzjU+Hl BJcAn0Me307KLqv4/ziq+Ln6TDHe00A3 =jdmn -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Sorry for the late reply. With 2.6.34-45 from Kernel:HEAD I have a general crash at ~[0.011...]. But I also see a "end trace" at top of screen ... With the older 2.6.34 and 2.6.35-rc2 I had/have the problem with inserted CD/DVD in most cases before the drm modules (radeon) become loaded. Btw. it seems that I cannot test more kernels before weekend because the idiots (or whatever I should name them) from Moobicent/Vodafone limited my "flatrate" connection to ~8 KB/s this month although they do not have the rights for doing so. So I have to fight also against them ... Johannes -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

I got it on another system with COM port: (last working kernel was 2.6.34-40-desktop) http://pastie.org/1010747

I have no idea how or if it works, but according to Documentation/serial-console.txt you can specify: console=lp0 as a kernel argument. /Per Jessen, Zurich -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
