Hi!
After update to 2.6.30-rc1, sharp zaurus c-3000 fails to boot with
white screen (with stripes). That's a regression w.r.t. 2.6.29.

What kind of white stripes? Does it look like the LCD controller
stops working or something.
There is a regression which caused X server hang during bootup,
with commit id 66c1ca0, which you can revert and have another
try.

As spitz also use cs_control for pxa2xx_spi, i believe that this is the
same issue i found wednesday.
See the "Kernel freeze caused by
a7bb3909b3293d503211d7f6af8ed62c1644b686" thread.

Ok, I'll try changing ASSERT->DEASSERT and see what happens. Hmm, it
now boots, with these messages:
WARNING: at kernel/irq/handle.c:366
BUG: IRQ handler called from non-hardirq context!
just after loading touchscreen device.
Thanks!
Pavel

Try reverting 044d408409cc4e1bc75c886e27ca85c270db104c as
software resent IRQs are sent from tasklet context, not from hardirq.
