Re: Temporary lockup on loopback block device

> On 2.6.23 it could happen even without loopback

Let's focus on this point, because we already know how the lockup
happens _with_ loopback and any other kind of bdi stacking.

Can you describe the setup?  Or better still, can you reproduce it and
post the sysrq-t output?

Thanks,
Miklos
