[-- Attachment #1 --] ah, sorry missed that. Will try that today. AHCI lasted over night with MSI off. Something I noticed, is that when the AHCI bus was timing out, it looked like the Xen Kernel was re-scanning the PCI bus. (Sorry, didn’t save these logs). I’ve love to dig into this further. Please let me know what/where to add some debugging code. - David P.

The great thing is now I got the Xen console working, so can get the debug output. However the bounce buffer/hypercall issue i would think is far more important than MSI interrupts at the monument. > > Glad to know you got it working at the end!
