[Xen-users] HP DL380G6 Debian Squeeze and esata

[Dominic Mason <dominic@xxxxxxxxxx>]

Hi

We have an HP DL380G6 and a StarTech PCIExpress esata card, which works
fine in plain vanilla Squeeze, and you can hotplug drives in with no
problems ie you get messages in kern.log, and a few seconds later a
fdisk -l will list the drive as /dev/sda, you can mount it, and read and
write to it.

However, when the debian packaged Xen Hypervisor is loaded, you get
absolutely nothing when connecting the external drive.

lspci shows

0a:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9123 PCIe
SATA 6.0 Gb/s controller (rev 11)

The BIOS identifies that card as a Marvell 88SE91xx

It's worth noting that if you boot the Xenified kernel without the
hypervisor loaded, then it works with no problem whatsoever, so it
doesn't appear to be an initrd problem.

We tried this on another 64-bit computer with a Gigabyte motherboard,
and also an old 32bit HP Desktop PC and there is no problem whatsoever,
so it appears to be an issue specifically with DL380G6 and Xen
Hypervisor


xm info tells me that the debian Xen version is:

xen_major              : 4
xen_minor              : 0
xen_extra              : .1

and we are running on the x86_64 2.6.32-5-xen-amd64 kernel


Can anyone shed any hint of a vague suspicion about resolving this?


Thanks
