That sounds very promising. Profiling may confirm suspicions about the need for a VDSO. > > Earlier Linux didn't work with Hatari emulator because its > (030) MMU emulation wasn't complete.

I suspect there may be issues on the Linux side relating to 68030; for a some time now I've been observing short lock-ups on 68030 (actually PowerBook 180). I get a lot of BUG splats in the kernel logs when I enable, CONFIG_LOCKUP_DETECTOR=y CONFIG_DETECT_HUNG_TASK=y CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_ATOMIC_SLEEP=y CONFIG_DEBUG_BUGVERBOSE=y Unfortunately I have too many other bugs to chase right now, but I'd be interested to know if you see any issues like this on Hatari or other platforms. -- > > > - Eero -- To UNSUBSCRIBE, email to debian-68k-requ...@lists.debian.org with a subject of "unsubscribe".
