kernel panic with 2.6.0-test6-mm4 and nptl

[Markus Schoder]

2 out of 3 times I got a kernel panic when running the tst-eintr1
test from current glibc (CVS) and nptl 0.60. It also happens
sometimes during normal usage.

I used all features defined in sysdeps/unix/sysv/linux/kernel-features.h
of glibc.

The message is `Fatal exception in interrupt'.  The stack trace
looked like this (from memory)

do_page_fault+0x0/0x50c
do_page_fault+0x41/0x50c
do_page_fault+0x0/0x50c
error_code+0x2f/0x50c

repeated 100s of times (infinite recursion?).

Machine is an Athlon XP 2000+, 768MB RAM, no modules loaded.

On one occasion I experienced a similar panic with 2.6.0-test6 plain
when using the same glibc but I could not reproduce it.
