Unfortunately, the issue is still the same.
I'm mapping everything from _stext & L4_PAGEMASK to _end & L4_PAGEMASK
after having mapped the pager to my new task, but each time one of my
created threads is still waiting for '1b'.
Besides, I'm getting a huge list of kernel warnings with the new
l4_fpage call that hasn't been there before. I've attached it to this mail.
So basically it's still the same code that I've sent you on September
5th, but in addition, there's the following loop beginning at line 57 in
lib/src/edft.c now:
