I tested by reinstalling the old glibc-2.9, rebooting test kernels, and
rerunning offending mutex tests from the glibc-2.9 test suite. I needed to
reinstall the old glibc because the new glibc-2.11 wants kernels in the
2.6.31 series or later.
The problem first appears in 2.6.31 and persists through the current
2.6.31.6.
The problem does not appear in 2.6.29 and 2.6.30 versions.
Yours,
Joseph
