I failed to stop this module loading using BrokenModules= so instead renamed it as vt6655_stage_DONOTUSE.ko - now system boots. So the finger of blame points squarely at vt6655_stage.ko -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Copied /usr/src/linux... to /usr/src/linux-rpm & chown'ed that to user rpm. Now I try to apply patch: "Error, can't find file to patch". Indeed there is no directory under /usr/src/linux... called "wireless-testing" Do I need something else as well?

Larry's private email was enough for me to get the make going, it started at 07.15 (UK time) yesterday and was still going when I went home some time after 16.00 - I came in this morning and it had run out of disk space (8G CF card). AARGH. A 500 MHz CPU and 8G CF are more than enough for the project needs but I'd overlooked issues like this when specifying the board. So now I will free up some space and try again, but it's unlikely to complete before I go home -> Monday before I can report success or otherwise. So I'll leave status as NEEDINFO until then. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The only trick is that the "make modules_install install" part has to be done on the target machine. The compilation can be done on any machine, even if the architecture is different. The necessary step in that case is to use the ARCH argument in the make command. For example, when I build an i386 system on a computer running an x86_64 version of Linux, the make step becomes "make ARCH=i386". One additional speedup: If the build host is SMP, then add "-jX" to the make, where X is the number of CPUs + 1. That puts a compilation on each CPU plus one job for control. It really makes a difference. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

"WARNING: GRUB: GrubDev2UnixDev: No partition found for /dev/sda with 2" It had not completed the Grub installation, so I did this myself using YaST. New kernel seemed to run exactly the same as the old one (-> as expected, the patched module still blacklisted). Next I removed the blacklist for vt6655 and re-booted (yes, I chose the new kernel) - same kernel panic though as before. I'd be delighted to try a different patch, might be a bit quicker now I have it set up but still > 1 working day to build from clean! I will very be tempted to build on another host as suggested above.

Then make and "sudo make modules_install" to re-build. It's a holiday weekend coming up and I know we're going to have a power outage so I will try to do a build from scratch at home.
