Hi Jiao, It appears as though the the web page is a little out of date. I'll update it with the contents of this e-mail in a few minutes.
The patches repository on the website is a mercurial queues repository that is supposed to patched on top of the linux mercurial repository. The correct way to use the patches repository is the following #Get a copy of the linux-2.6 mercurial repository hg clone http://www.kernel.org/hg/linux-2.6/ #Get a copy of our patches to linux cd linux-2.6/.hg hg clone http://repo.m5sim.org/linux-patches/ patches #Return to the root linux directory cd .. #Update the linux source to the desired version (can take 5 minutes) hg update v2.6.XX #Select tho appropriate patches for the version of linux you selected (currently 13,16,18,22 are available in the linux-patches repository) hg qselect 2.6.XX # Apply the patches hg qpush -a #Copy the default configuration file, so it's used cp .config.m5 .config #Compile the kernel (assuming compiler is in $PATH, otherwise full path would need to be specified) make ARCH=alpha CROSS_COMPILE=alpha-unknown-linux-gnu- vmlinux Now the above listed versions of linux should compile just fine. I doubt that the two problems you see running the kernel (hanging and loosing an interrupt) have anything to do with the kernel you've compiled. You can try the steps above to be sure, but its probably either a bug in your changes or a bug in M5. Briefly what area do your changes modify? Are you running with caches at this point? Multiple processors? If so there were some bugs in 2.0b4 that could potentially be causing that problem. Would it be very difficult to switch to a newer version of m5?
