Need help determining package to file bug against
 

I am seeing odd behavior running a Xen 4.0.1 on AMD64 (squeeze)

I am running open-iscsi to connect to a lun, and then using this lun
as a phy type backing store for a xen hvm guest.

Disk performance works well from dom0 directly (mkfs.ext3 proceeds at
a reasonable speed) but when I try do a install from the hvm guest
(debian amd64 netboot (PXE)) the disk speed slows to a crawl and
messages like:

(XEN) grant_table.c:1956:d0 Could not get src frame 207949
(XEN) printk: 481 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 2079b0
(XEN) printk: 670 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 207647
(XEN) printk: 481 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 2076ae
(XEN) printk: 603 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 20772b
(XEN) printk: 563 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 2077a9
(XEN) printk: 588 messages suppressed.
(XEN) grant_table.c:1956:d0 Could not get src frame 207c25

appear in xm dmesg

I've repeated an identical install process using the i386 version of
the pxe/netboot installer without any issue.

Any suggestions on where this bug should be filed?
