Hi Michal,
It is strange that there is no further output, although I am worried about the IOMMU faults that happen just prior to that. On some systems certain devices (notably USB controllers) can lock parts of the system if they are unable to function correctly. My suggestion would be to resolve those IOMMU faults first.
If I had to guess the IOMMU faults you are seeing at the end of log are from the USB controller. Typically most boot loaders that load off USB leave the controllers active after performing the boot, whilst seL4 assumes that all devices are inactive such that it can safely enable the IOMMUs.
My suggestion therefore is try and boot your image from the flash storage or over the network via PXE and see if that resolves the faults.
