Can you add your .config here? pseries_defconfig boots fine for me with the same kernel. I wonder if CONFIG_IRQSTACKS isn't enabled. I used arch/powerpc/configs/pseries_defconfig and, still, the system continues to fail while booting.
In both this configuration file and the one I was using originally (which I'm attaching), CONFIG_IRQSTACKS is enabled.
Just in case, LILO configuration entry for the kernel is:
image = /boot/vmlinux-2.6.34-vjj
###Don't change this comment - YaST2 identifier: Original name: linux###
label = 2.6.34-vjj
append = " quiet sysrq=1 insmod=sym53c8xx insmod=ipr"
initrd = /boot/initrd-2.6.34-vjj
root = /dev/disk/by-id/scsi-35000c500077a329f-part3
The new output for the error is:

The system continues entering the monitor, and when exiting generating new error output, but I just truncated at this point. If necessary, I can try to boot again and attach the complete output.

Thanks for reporting this, it looks like a real issue. Could you give the patch here a test: http://patchwork.ozlabs.org/patch/54353/ Thanks for the patch. I could not try the system for a long time yet, but it booted correctly and everything seems to be working nicely. Thanks again! |
I have an IBM POWER6-based system (IBM BladeCenter JS22), running SUSE Linux Enterprise Server 10 (SP2). While kernel version 2.6.33.3 works fine, 2.6.34 fails at boot. I have tried several versions (pre-stable, stable 2.6.34, and 2.6.34-git16) but all of them failed. The error I am obtaining is the following one (the output is for 2.6.34-git16, but I get basically the same with 2.6.34 (stable)): === error output begin === Starting ipr initialization daemon done
