I am unable to reproduce any such errors in my test using kernel 2.6.8.1 and
loop-AES-v2.1c and ext3 file system on my x86 test box.

I have tested loop-AES using mregparm=3 in my earlier tests, and they worked
ok. gcc version in those tests was 3.3.2 . Today's test kernel was compiled
with Debian woody gcc-2.95.4, and no mregparm=3 was used.
I quickly browsed through ext3 changes from kernel 2.6.7 to 2.6.8.1, and I
did't see any obvious change that would cause this problem.
loop-AES-v2.1b to loop-AES-v2.1c changes include addition of two missing
flush_dcache_page() function calls to loop code, but on x86 that function is
defined as no-operation:
# grep flush_dcache_page include/asm-i386/*.h
include/asm-i386/cacheflush.h:#define flush_dcache_page(page) do { } while (0)

Please let me know how that works out.

2.6.7+loop-AES-v2.1b or 2.6.7+loop-AES-v2.1c ?
