long-term 7600-booting patch

[Thomas Capricelli]

Hi, 

	I've reported this problem many times to linuxppc support,  Paul
Mackerras and some others.

	Since may 1999, my kernel won't boot UNTIL I applied a patch I have
available to anyone who wish.

	The problem (well known) is with the first (internal) SCSI not syncing
at boot time.

	As my 2.1.125 kernel from linuxppc R4 was always fine but I need to
boot new kernels, I've made this patch. Not that I understand a lot of what
i've done, mainly backporting the mesh code from 2.1.125.

	At least, my mac now always BOOT. Before applying this patch, I had to
try between 6 and 16 times to boot my computer. You DON'T know how tiring this
is

Thomas

Can you please try a 2.3.x kernel? I suffered from a similar problem and it was
solved in 2.3.x.

when I'm talking to journalists I just say "programmer" or something like that.

	I'm having a close look at 2.3. Recently (2.3.21 I guess), one very
small part of my patch wasn't needed anymore because it was part of it.

	It does work very well with latest 2.3.x + my patch. I haven't tried
whithout it, though. 
	I'll try and tell you soon.(tomorrow probably)

sincerely,
Thomas

	My macintosh still won't boot with 2.3.24 until my pacth is applied.
This problem is here since march, 1999. on all >2.2.0 kernel.

	Also, the stock-linux-2.3.24 is really a pain to compile. The kernel won't link
until pmu is added (pmu is powerbook-related stuff), and some other minor
problems.
	Also, I don't dare to compile anything as module anymore, cause most of
them won't link when insmod'ed. (unresolved symbols such as memcpy...)

	Those two last problems are here since at least 2.3.18, probably  much
more longer.
