The kernel is 2.6.32-05775-gaad3bf0-dirty now.
This is my fix to avoid bdi_sync_writeback().

The problem is somewhere in sync/cache code.

It seems files are in the cache but not on the server storage.
Then I do `sync` and make
orion linux-2.6.31.6 # make -j4
scripts/kconfig/conf -s arch/x86/Kconfig
*** Error during update of the kernel configuration.
make[2]: *** [silentoldconfig] Error 1

Does it support symlinks ?
Ok,
cd include
rm asm
cp -r asm-x86 asm
cd -
make
*** Error during update of the kernel configuration.
Failed because of:

It can't update .config
But it _is_ on the server:
r...@tor ~ # ls -la /mnt/z/linux-2.6.31.6/.config
-rw-r--r-- 1 root root 67606 Dec 12 02:31 /mnt/z/linux-2.6.31.6/.config
but not .config.old
---
Can't reproduce now the situation when the client said ENOENT while
the file was on the server.
Client's dmesg is too noisy to find something useful.
