2.3.99-pre7-1: BUG in mount.h:41

Hello,

at the start of runlevel 2 i see segmentation faults starting when
enabeling dummy0/eth0. The syslogscreen displays a lot OOPS'es and "BUG in
mount.h:41"
Noting is actual successfull in the runlevel 2 scripts, and i can't login,
and errors are not logged.

The actual code in mount.h:
static inline void mntput(struct vfsmount *mnt)
{
        if (atomic_dec_and_test(&mnt->mnt_count))
                BUG();
}

my kernel is a "anything as module" type, and i use IDE/SCSI + LVM (SuSE6.4)

2.3.99-6 works OK (except for the VM/IO issue)

I assume it's triggered when reading/executing from an ext2-fs on LVM
