After the integration of 4705093 the regression test sun/security/provider/SeedGenerator/Fips.java fails on some Linux platforms/kernel versions (e.g. RHAS 2.1):

Exception in thread "main" java.security.ProviderException: generateSeed() failed

The reason is that reads from /dev/random do not block until all requested bytes are available as expected.

Note that this affects applications explicitly calling generateSeed() to obtain large amounts of seed material only.

Also causes JCK test api/java_security/SecureRandom/SecureRandomTests.html#misc to fail.
