[iPAQ] pivoting and flash booting problems?

Hi,

I've been seeing some strange problems on a H3600.

- I've configured it to pivot_root from the ipaq's flash to a 256
SanDisk CF card. However, I have seen a couple of problems. I
frequently get log entries claiming invalidate problems. Any ideas
on how to get rid of these?

invalidate: busy buffer
invalidate: dirty buffer
invalidate: busy buffer
invalidate: dirty buffer

- I've also been trying to get the ipaq to boot the CF card
directly. I've used the instructions from the Wiki
BootingLinuxFromCF, but no luck. It refuses to do anything after
finding the kernel. Looking through the logs I notice that the
pcmcia insert stage doesn't correctly display the name/revision of
the card (despite retrieving them correctly from under Linux). So
perhaps 256M cards (SanDisk) aren't supported under bootldr
2.18.39? I've included my boot log entries below. I'd really like
to get this is going and forget pivoting, but I'm not having much
luck.

... then an ominous silence? ...

PS: I manually typed the line "set kernel_filename ..." because it
doesn't seem to be evaluating the boot/params file either?
