[BUG 2.6.20-rc3-mm1] raid1 mount blocks for ever

Jens: can this be a plugging issue?

The following command seems to block for ever:
# mount /home

It is an ext3 fs on top of /dev/md0, RAID1.

The call trace is:

My precious data!
After that, the system just refuses to shutdown or sync:

http://userweb.kernel.org/~akpm/2.6.20-rc3-mm1x.bz2 is basically 2.6.20-rc3-mm1,
minus git-block.patch.  Can you and Torsten please test that, see if the hangs
go away?

Thanks.

Works for me too.

I used the following kernel commandline:
root=/dev/sdb6 console=ttyS0,38400 console=tty1 lapic rootflags=nobarrier

I also added nobarrier to the fstab entry for my root.

Just to mention it: My system does not use any RAID devices, not even the 
drivers are getting complied.

Ok, thanks for testing, I'll try and reproduce it locally.

Does this fix it? Only apply this one, not the patch from 7775.

2.6.20-rc3-mm1 plus your patch works for me.

Lucky enough to found this before giving up:

        mount takes 39s, and umount takes 42s.
