Hi Paul san
When I set rootfs in USB memory,
the latest kernel seems to have a problem.
Please refer to log for the error.
(AP3300(ap325rxa) is the same phenomenon, too.)
- NFS boots both boards normally.
- Both boards were confirmed a USB boot in the old kernel.
(2.6.27 and 2.6.31-rc7)
- rootfs is made by Debian and uses the following things.
https://oss.renesas.com/modules/download/index.php?cid=61
"debian-rootfs-20091208.tar.bz2"
Do you recognize this problem?
Thanks,
Goda

You should rebuild your kernel with verbose BUG reporting and all of the
kallsyms bits turned on, which will give you a meaningful oops. That
should at least give us an idea of where things are going wrong,
otherwise we go back to bisecting.

This problem seems to occur with the following commit.
commit 2277ab4a1df50e05bc732fe9488d4e902bb8399a
sh: Migrate from PG_mapped to PG_dcache_dirty.
Sorry, I cannot identify it to number of lines.

I suspect the PG_mapped behaviour just ended up hiding the problem by
doing far too aggressive flushing. PG_dcache_dirty takes a more subdued
approach to lazy writeback, which only trips us up when someone has
called in to update_mmu_cache() without the pages having a chance to be
flagged as having dirty dcache lines.
USB mass storage appears to be one of these beasts, but there doesn't
seem to be any good way around this without just walking over the URB
transfer buffer and making sure that flush_dcache_page() gets called for
each page. Doing this in the HCD is unfortunate, but there doesn't seem
to be any better place for it. Likewise, it's really only mass storage
that really has this problem, so it ends up with superfluous flushing for
all of the other cases.
The attached patch fixes these issues up for me, along with a spinlock
recursion bug in the HCD driver (r8a66597_check_syssts() specifically),
tested with an SSD over USB running XFS on SE7724. This is based on a
patch by Catalin Marinas doing the same thing for isp1760-hcd.
Note that this only impacts HCDs using PIO. Any of the others (like
ohci-sm501) that are using the DMA mapping ops already have their cache
handling taken care of through the DMA mapping API.
If this works for you, I'll split the patch up in to the locking fix and
the cache handling fix and check them in once Shimoda-san Acks them.
