RE: [Xen-users] asus P5B Delux not booting xen (ACPI problem?)

[Steve Brueckner <steve@xxxxxxxxxxxxxx>]

It's a common problem with Xen that it doesn't support new hardware (e.g.,
965 boards) very well.  This is because Xen is based on older vanilla kernel
versions and 965 support requires a >2.6.19 vanilla kernel or else
distro-specific drivers.  Furthermore, there is no easy way to upgrade the
Xen kernels.  I had the same problem as you, although I use Fedora instead
of Debian.  It's great that you're able to solve your problem using an older
version of Xen incorporated in Debian's packages.  

I'm just commenting in this thread to make some noise about the problem.
I'm hoping Xen will release a 3.1 version with a newer kernel, or else make
it easier for users to upgrade their own kernels.

Hi,

I'm going crazy trying to get Xen running on an ASUS P5B Delux (latest BIOS
installed).

I've tried xen-3.0.4 and xen-3.1.0 (both compiled from source)

The boot process stalls with
ACP: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (low level) -> IRQ 18
ahci: 0000:00:1f.2: AHCI 0001.0100 32 slots 6 ports ? Gbps 0x3f impl SATA
mode
ahci: 0000:00:1f.2: flags: 64bit ilck stag led pmp pio
ata1: SATA max UDMA/133 cmd 0xE102E900 ctl 0x0 bmdma 0x0 irq 18
ata2: SATA max UDMA/133 cmd 0xE102E980 ctl 0x0 bmdma 0x0 irq 18
ata1: port is slow to resond, please be patient
ata1: failes to respond (30 secs)
scsi0 :ahci
ata2: port is slow to resond, please be patient
ata2: failes to respond (30 secs)

booting xen-3.1.0 adds some more info to the failure:
ata1: SATA link up 3,0 Gpb (SStatus 123 Scontrol 200)
ata1: qc timeout (cmd 0xec)
ata1: failed to identify (I/0 error, err_mask = 0x0104)
ata1: port is slow to resond, please be patient
ata1: failes to respond (30 secs)
ata1: COMRESET failed, device not ready
ata1: hardreset failded

But this doesn't always happen. 50% of the time, the process stalls for
about 6 secs on
ACP: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (low level) -> IRQ 18 And then
continues correctly.

I've tried passing acpi=off to the kernel but this results in ExtINT not
setpup in hardware but reported by MP table.

When I boot this machine with vanilla debian etch, there are no problems.

Any ideas?
Thanks.
Chris.
