Xen devel - Nov 2007 - domU does not attach disk under periods of high IO?

Hi all.  I''ve noticed issues with domU kernels not attaching to their
disk
device at bootup under periods of high IO (per my bug report at
http://bugs.centos.org/view.php?id=2317).  This also occurs under Fedora
Core 8 dom0 which is on a build of Xen 3.1.  As I''ve inquired about
this to
xen-users with no response, I''m curious if this is a known issue and
if/when
you guys plan on addressing it.

Sincerely,

Ray Barnes

There was a bug in the kernel xenbus implementation where blkfront would not
wait for partition tables to be parsed before signalling that a device
connection was Œready¹. Take a look and see if your blkfront.c in your
kernel has a function called Œblkfront_is_ready¹. If not, then you need
changesets 82 and 217 from http://xenbits.xensource.com/linux-2.6.18-xen.hg

There have also been problems with a buggy version of nash. I can¹t remember
the precise details right now unfortunately.
