Re: New oskit-mach debugging log - failed assertion 'port->ip_srights > 0'
Hi, mission accomplished. ${root} and $(task-create) are NULL.
I don't fully understand how this works, so the ball is in your
court.

Ok, so there is a bug in the boot script cleanup handler. It should
probably be more helpful. ;)

You are using the less tested new method of booting. As a work around, you
might want to try to use the old serverboot method of booting. But please
keep on track of this problem, so we can fix it! (We want to get rid of
serverboot asap). Dig out any of the older installation instructions how to
boot with serverboot.
I tried this. It gets a bit further along and then hangs when it tries
to initialize /hurd/ext2fs.static -- but first things first.
The interesting part for me is not so much why the assertion fails, but why
you get into the cleanup handler with ABORTING == 1 (see frame #5)
error 5 is (kern/boot_script.h):
#define BOOT_SCRIPT_UNDEF_SYM 5
We should use an enum here so it is more apparent. So it hit an undefined symbol
in boot_script_exec, line 560, which means it could not resolve a variable.
Set a break point at that line and see what ARG, SYM etc look like (eg where
in the boot script parsing it fails).
Somehow it doesn't like your GRUB boot configuration. You should be able to
find out what it is and how to fix it, but you should also try to fix the
other, deeper problem so other users get a more helpful response than an
instant kernel reboot ;)
Ok, I did this. It appears that everything after "-T typed" is getting
lost; i.e.
${root} and $(task-create) are equal to ""
Here is my script capture.
