I felt that my previous message doesn't have any detail info. Sorry for
that.

Herewith I came back with better info

1. PCSC-lite support patch is on the way, I will submit once the testing
completed, I would love to share with anyone who interested in
2. Buildroot version: buildroot-2011.02 from git
3. External toolchain from Code Sourcery 2010.09
4. Running kernel on the target linux-2.6.28.6

I also tried to rebuild everything using buildroot toolchain with linux
headers 2.6.37.2, but there is no change.

I suspect that the root cause is the running kernel on the target taking
into account using different toolchain (and different pthread library) there
is no difference.

I really appreciate any feedback/suggestion from all of you.

Thanks in advance,
