Hi,

I have a linux binary I=E2=80=99m trying to run on a 12-CURRENT machine =
with the linux_base-c7 (64-bit) port.

When trying to run it, it starts up and then spits out this error:
shm_semaphores_init: semctl init error: Bad address - trying again

I=E2=80=99m guessing that it=E2=80=99s reaching the end of the switch =
statement in sys/compat/linux/linux_ipc.c=E2=80=99s linux_semctl(=E2=80=A6=
) function and getting an EINVAL result.  That=E2=80=99s a guess, =
however, as I don=E2=80=99t know enough about debugging at this level in =
order to tell what it=E2=80=99s actually doing.

Can anyone tell me how to get the results of the linux_msg() call at the =
end of the function to find out what ipc type it=E2=80=99s trying to =
utilize, and with a little luck maybe get a patch created to support =
whatever operation it=E2=80=99s trying?

Thanks,
-Joe
