Xen users - Sep 2005 - xen-2.0.7 don''t boot on my hpt370/372 (raid enabled)

Hi,

wenn I boot my xen-2.0.7 with my 2.4-xen0 kernel it comes the following error 
  PCI: Found IRQ 11 for device 02:06.0
an the machine make a reboot :(

This IRQ shoud be the raid-controller.

Under xen-unstable the error does not seem to arise, but it unfortunately gives
for this no 2.4 kernel :( and I can''t no build one (build errors) and
2.6 don''t support this kind of raid :(

please help me and excuses the bad english (I hope you understand me)

Sebastian

xen is sensitive about irq-sharing on some hardware, try to disable everything 
on the same IRQ, or assign it other IRQ lines.

hpt370/hpt372?

I don''t know where you looked for it, but my 2.6 kernel sources have an
driver
for it just fine:
(excerpt of the Help for the option:)

 CONFIG_BLK_DEV_HPT366:
HPT366 is an Ultra DMA chipset for ATA-66. 
HPT368 is an Ultra DMA chipset for ATA-66 RAID Based.
HPT370 is an Ultra DMA chipset for ATA-100.
HPT372 is an Ultra DMA chipset for ATA-100.
HPT374 is an Ultra DMA chipset for ATA-100.
 Depends on: XEN_PHYSDEV_ACCESS && IDE && BLK_DEV_IDE &&
BLK_DEV_IDEDMA_PCI
-> Device Drivers 
 -> ATA/ATAPI/MFM/RLL support 
  -> ATA/ATAPI/MFM/RLL support (IDE [=y])
   -> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (BLK_DEV_IDE [=y])
    -> PCI IDE chipset support (BLK_DEV_IDEPCI [=y]) 
     -> Generic PCI bus-master DMA support (BLK_DEV_IDEDMA_PCI [=y])


So maybe try a 2.6 xen-ified kernel with that driver.

as per bios and WinXP only the HPT370 (MassStoreageControler) has this IRQ - 
or any other method see to the allocation?
