I am trying to get a remote gdb kernel debugging session and on the Target macine I get the following error: "Fatal trap 12: page fault while in kernel mode" .. fault vurtual address = 0x26 fault code = supervisor read, page not present" is anyone else getting this as well ?? There is a thread in -Current last June sometime, with the "fix" being to add the following line to the config file: ............ Turns out the workaround is to use DISABLE_PG_G. Two things made me try this. One: In his commit of pmap.c and locore.s on 7/12 7:56 Peter had this to say: +-- |- Try and fix some very bogus PG_G and PG_PS interactions that were bad | enough to cause vm86 bios calls to break. vm86 depended on our existing ... |New option: DISABLE_PG_G - In case I missed something. ---------------------\ This did not fix the problem thought, any other ideas appreaciated!!
