and I check the host linux configuration. the page offset is CONFIG_PAGE_OFFSET=0xC0000000 which is correct as your suggestion.I guss that fiasco-ux must be failed to interpret ELF of sigma0/roottask/irq0 and execute it . I put the same "hello" bin in grub/ fiasco environment. it works fun. JDB does not help me becuase that fiasco-ux enter a stage that CRTL-C does not work, I can not bring the system to jdb stage with CRTL-C. ps can find three processes which are 'fiasco-ux,[I][irq0] and [fiasco-ux]. I can use strace for fiasco-ux and [i][irq0]. but failed to trace [fiasco-ux].
Thats correct, as the fiasco-ux is already ptracing the [fiasco-ux] binary. I think you haven't shown us the full log of the segfault and the text before yet, so please post it. We should be able to see more when we see the log.
