For me the patch seems to work. The system boots correctly and is now working for hours. But unfortunately it doesn't make any changes to my problem. > I think it just doesn't properly determine processor types because it > doesn't > associate the information it gets from the cpu with the appropriate > strings. > From what I can tell it is insignificant. > > If the patch doesn't help, can you explain in more detail exactly what > the > problem you're experiencing is? So, okay. The big problem is that my two isdn-cards are only working in dom-0. When I hide them from dom-0 and create a driver-domain the drivers load correctly but the cards are not working. In dom-0 my testapplication (which just calls a telephone) works and a phone is ringing. when starting in the driver-domain, the programm starts, no phone is ringing and after a few seconds a timeout ends the app. I think it might be an irq-related problem. I found that all my pci-devices share irq 5 and 11 under xen and that there I only have 15 IRQs (see 1st post). Starting Linux natively there are much more IRQ used. So I thought it might have something to do with apic-initialisation. Even after applying your patch I only see the first 15 IRQs. I can supply you with debug-information if you like/need. Patrick
