[parisc-linux] c110 panic when try to boot 2.6.10-rc1-pa11?

[Joel Soete <soete.joel@tiscali.be>]

hello pa*,

2.6.10-rc1-pa10 works fine on this c110 (as soon as I don't try to use the narrow se crtlr)

unfortunately 2.6.10-rc1-pa11 failled to boot with following message:

Too bad :(

the diff between src trees is very small:

=========><=========
(this last one doesn't affect c110)

I first suspected the more complex i.e. memcpy.c and revert it first but it doesn't help :O

OTC reverting the second one (i.e. init.c) help a bit in the way the system boot again but wrongly as you can judge by your self 
with following init errors:

Not starting GNOME Display Manager (gdm); it is not the default display manager.

I didn't analyse in much detail but eg /etc/X11/default-display-manage exists but it's name seems to be longer:
# ll /etc/X11/default*                                                                                 ls: 
/etc/X11/default-display-manageß: No such file or directory

Randolph: any idea?

Thanks in advance for attention,
	Joel
