up on systems that have Zorro I/O space allocated outside the Z2 I/O region, and then only if kvm usage is high enough to begin allocating pages already mapped for hardware mappings. Found and fixed by Niklas Hallqvist on OpenBSD. From niklas@cvs.openbsd.org: Yay! This fixes a bug that has been there since day one of the amiga port. We have never protected the kvm area that maps Zorro I/O registers in the Z2 memory space from being allocated by the kmem_* routines. Lately kvm usage has increased and we have needed more kvm allocated than earlier thus this area have got allocated with random results. Most often resulting in MMU fault panics, but also in hangs. This bug has stalled the amiga port release builds for several weeks, but now I *hope* the amiga will have a chance to be built and tested in time for 2.3. |
