Hello, for the first time I tried to boot a xen kernel from devel with a NetBSD PV dom0. The kernel boots, but when the first userland prcess is launched, it seems to enter a loop involving search_pre_exception_table() (I see an endless stream from the dprintk() at arch/x86/extable.c:202)
With xen 4.13 I see it, but exactly once: (XEN) extable.c:202: Pre-exception: ffff82d08038c304 -> ffff82d08038c8c8 with devel: (XEN) extable.c:202: Pre-exception: ffff82d040393309 -> ffff82d0403938c8 (XEN) extable.c:202: Pre-exception: ffff82d040393309 -> ffff82d0403938c8 (XEN) extable.c:202: Pre-exception: ffff82d040393309 -> ffff82d0403938c8 (XEN) extable.c:202: Pre-exception: ffff82d040393309 -> ffff82d0403938c8 (XEN) extable.c:202: Pre-exception: ffff82d040393309 -> ffff82d0403938c8 [...] the dom0 kernel is the same. At first glance it looks like a fault in the guest is not handled at it should, and the userland process keeps faulting on the same address. Any idea what to look at ? -- Manuel Bouyer <[email protected]> NetBSD: 26 ans d'experience feront toujours la difference --
