In the past few days I have attempted to get 2.6 kernels booting on my
diskless MVME167 boards.
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:

... but I never got any ;)
Bummer...
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.
OK. Can I add your Tested-by? Then I'll forward it to Linus ASAP.
Yes, no problem, if your patch would look something like this (I like
Yes it does.
git already!):
Good!
