[Pkg-xen-devel] Bug#710522: xen-hypervisor-4.1-amd64: Boot hang with Linux 3.2+Xen, works with linux 2.6.32+Xen or 3.2 raw

Fri May 31 15:38:59 UTC 2013

Package: xen-hypervisor-4.1-amd64
Version: 4.1.4-3+deb7u1
Severity: important

Dear Maintainer,

We are having a problem on several Supermicro servers (I'll include more details 
on the configuration later) : when booting Linux 3.2 linux-image-3.2.0-4-amd64 
(Wheezy) as a DOM0 on Xen 4.1 (xen-hypervisor-4.1-amd64 from Wheezy), the system 
hangs after :
[    3.716174] scsi1 : ata_piix
[    3.722116] scsi2 : ata_piix
[    3.728407] ata1: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0x1860 irq 14
[    3.742390] ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x1868 irq 15

The system boots properly when booting either Linux 3.2 without Xen, or when booting
Linux 2.6.32 (linux-image-2.6.32-5-xen-amd64 from Squeeze) on Xen. 

I tried with Xen 4.0 from Squeeze (xen-hypervisor-4.0-amd64) the behavior is the
same (it hangs with Linux 3.2).

The systems are all running 2 quad-core Xeon (E5320 or E5405) with 32Gb to 64Gb of RAM,
with Supermicro X7DB8 motherboards.

With have a test server on which the problem shows, so feel free to ask for additional 
tests or any information which may be useful.

We'll try to hunt down the bug by running additional tests, but we would welcome any hint
on what to try to find it.
