Subject: 2.6.39.1 Regression: testsuite failures in eglibc on Alpha

While building eglibc (Debian version 2.13-5) test suite failures are
reported when running under the 2.6.39.1 kernel, but not when running
under the 2.6.38.6 kernel on the Alpha arch. The failures are:

tst-mutexpi4.out, Error 1
tst-mutexpi7.out, Error 1
tst-mutexpi7a.out, Error 1
tst-robust1.out, Error 1
tst-robust3.out, Error 1
tst-robust4.out, Error 1
tst-robust6.out, Error 1
tst-robust7.out, Error 1
tst-robust8.out, Error 1
tst-robust9.out, Error 1
tst-robustpi1.out, Error 1
tst-robustpi3.out, Error 1
tst-robustpi4.out, Error 1
tst-robustpi6.out, Error 1
tst-robustpi7.out, Error 1
tst-robustpi8.out, Error 1

Some of the above tests time out, for example:

Timed out: killed the child process
make[3]: ***
[/?BUILDDIR?/eglibc-2.13/build-tree/alpha-libc/nptl/tst-mutexpi7.out]
Error 1

Since no problems are seen with the 2.6.38 kernel series this appears to
be a 2.6.39[.1] regression.

Cheers
