I'm seeing some weird behavior in 2.6.30-rc1 that didn't exist in
2.6.29.
We have a slightly older LTP version (20080131) that we run on some
embedded PPC boards. If I run the syscall tests on 2.6.29 things pass

Will try to repro on a normal machine, but can you attach the
/proc/pid/status
(and possibly the stack) of the parent of the 'recv01' ?

Name: recv01
State: Z (zombie)
Tgid: 2449
Pid: 2449
PPid: 1

Ok, but I meant the status of the parent (i.e /proc/1/status in this case).

To get the stack, if CONFIG_MAGIC_SYSRQ=y, you can:

$ echo 1 > /proc/sys/kernel/sysrq
$ echo t > /proc/sysrq-trigger
$ dmesg > /tmp/dmesg.out

Look in /tmp/dmesg.out for the process stack
