2.6.39-rc2 on zaurus: does not build, does not boot

[Pavel Machek]

Hi!

Build fix is below. Maybe it is pending in the trees somewhere
already...

Boot stops just after mounting root filesystem; cursor stops
flashing. (Any idea what goes on there?)

Fix is already there, it was broken by a patch from someone recently. Thanks 
though

No idea, it works for me and doesn't hang ;-)

With CF bluetooth unplugged, it gets  up to userland.

Once it hung in eaarly boot, once early in runlevel 2.

Hmm, the cf seems to be crippled a little.

I've got oops in pccard, but only when cf wifi is compiled in kernel and
inserted while booting, it stopped when the driver is compiled as module.

Note that zaurus has two cf slots, one for internal hd and one outside, so it
may be some race in cf/pccardd initalization.

Some parts of the trace:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] mpad=00000000
Internal error: Oops: f5 [#1] PREEMPT

Which seems like problem occured in complete() ...

I broke it accidently, sorry :) you can enable CONFIG_FB_PXA_OVERLAY as 
temporary workaround

I had problems mounting filesystems; good news is that in 2.6.39-rc5
these are fixed.
