marius 2008-09-13 15:17:23 UTC FreeBSD src repository Modified files: (Branch: RELENG_6) sys/sparc64/sparc64 autoconf.c Log: SVN rev 182998 on 2008-09-13 15:17:23Z by marius MFC: r182688 Bypass isa_probe_children(9) and directly call bus_generic_attach(9) in order to avoid the invasive probes done by identify-routines of ISA drivers, which may access unassigned addresses or those of unrelated devices and thus in turn can trigger master/target aborts as revealed by r182108 and ahc(4). I think that this is also the cause of the hang previously seen on B100 blades during boot. Bypassing isa_probe_children(9) also avoids adding ISA hints, which just can be wrong for sparc64. Approved by: re (kib) Revision Changes Path 1.13.2.1 +7 -1 src/sys/sparc64/sparc64/autoconf.c
