I don't have the right filesystem in front of me to debug, but this recipe should work for debugging PID 1 with gdb (assuming you have a platform already set up with a populated root filesystem etc.): Connect a keyboard and monitor before booting.

@dave, could you open a new bug for klibc ? this bug is not klibc related. busybox-initramfs links against glibc and given that busybox' exec behavior changes if we use -marm or not this one is rather a toolchain one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683683 Title: run-init on omap3, omap4 in natty dies if busybox is built with -marm -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@michael,if you only want to debug a running initrd you dont need to repack it, just boot with the break= option (some of the valid values are: top, premount, bottom). that way you can get a shell inside the initrd, do your debugging tasks and go on booting with ctrl-D note though that in case of run-init this wont help a lot, since run-init can only be started by pid 1 (break spawns a subshell with new pid) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683683 Title: run-init on omap3, omap4 in natty dies if busybox is built with -marm -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@dave, ah, thanks, yeah, we should retarget it if that patch is complete now (note that this bug is just exposing a busybox issue, the run-init error is apparently just a side effect of exec misbehaving if busybox is built with -marm) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683683 Title: run-init on omap3, omap4 in natty dies if busybox is built with -marm -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
