initramfs linus tree breakage in last day

initramfs linus tree breakage in last day

[Jon Smirl]

When I boot the kernel is mistaking my initrd as an initramfs. Of
course this doesn't work. This broke in the last 24hrs on the linus bk
tree. I am using an up2date Fedora Core 3. Booting older kernels still
works.

This will let me boot again. It is not obvious to me where the problem
is, it may have something to do with netlink or maybe memory
corruption?

Cute.  I assume you have all the memory debug options enabled?

You could try disabling net features in .config, see if you can work out
which one causes it.

Question, what are the config choices for netlink?

OK, SMP, could you please try this patch by James Bottomley that fixes
a brown paper bag bug in my proto_register patch?
