hi,
as far as I recall, Fiasco used to re-enable interrupts upon returning from a syscall, even if they had been disabled before the syscall. Some of my old code (my patched version of L4Linux22 which I am using with nomadbios) seems to have relied on this behaviour and now fails with a "page fault in cli mode" on the first intruction after an IPC-operation.
Am I correct that the behaviour has been changed like this, or do I just have to configure my Fiasco differently? The old Fiasco I am using is from CVS about a year ago.
thanks, Jacob

Please disregard above message, seems to be something else to do with pages/superpages that has changed, must investigate a bit more.
