Sorry, I followed the bug report description stating "2 grave - makes
the package in question unusable by most or all users"

I don't know about the percentage of users affected, but for those who
are affected the problem is definitively grave. As I mentioned on Xen's
site: Most of my machines are neither affected, but the most recent two.
So I guess we will hear more about that problem in future.

Right. The dom0 kernel doesn't crash if it is booted without hypervisor
though, as mentioned in the bug report as well. Hence the problem must
be within the communication between dom0 and hypervisor, on whichever
side. As far as I could follow upstream devs, the hypervisor fails to
report DMA memory appropriately.

Right. As indicated Debian does not introduce that command line by now.
That results in a system being unable to be booted - which isn't such a
big deal if you have local access from POST and beyond, but is
particular bad on servers (where Xen is most likely to be used).
