I have tried several kernels, including: linux-image-2.6.26-1-mvme16x_2.6.26-9_m68k.deb. I traced the "freeze" of the kernel to the 'BUG_ON' test in 'm68k_setup_user_interrupt' in file arch/m68k/ints.c: BUG_ON(IRQ_USER + cnt >= NR_IRQS); Now, for the VME boards, IRQ_USER is 8, cnt is 192 and NR_IRQS is 200. So this test will trigger the BUG_ON action, and so the kernel appears to stop without logging any diagnostics.Oops, that looks like an off-by-one error. It has been introduced by commit 69961c375288bdab7604e0bb1c8d22999bb8a347 ("[PATCH] m68k/Atari: Interrupt updates").
Hm, no fair! I already reported this bug back in 2006, asking for feedback: http://www.nabble.com/Re%3A-CVS-Update%3A-linux-tt6999670.html ... but I never got any ;) By the way, I tested Linus' HEAD today (with your quilt patches, Geert) on my MVME167, it only needed the above fixed and it booted. I couldn't compile it with my old cross compiler (gcc version 4.1.3 20080623 (prerelease) (Debian 4.1.2-23)), it ICEed somewhere in net/sunrpc. The new cross compiler I built after that (gcc version 4.3.2 (Debian 4.3.2-1)) had no problems with it.
