I deinstalled linux-image-2.6.20-xen with dpkg -r and installed your kernel with dpkg -i

Could it be that something went wrong when compiling the kernel/building the package? Maybe no make clean before? Please let me know it I should do something different or if you have a new deb for me. I will also try the kernel options when you tell me which parameters I should test. I found the swiotlb option in some mailing list before and tried 65536, but I got a crash during boot time... Thanks, Timm P.S.: Sorry if you receive this twice.
