Well Murphy came calling today after my 10+ gig recording marathon yesterday
(recorded constantly from 11am til 6pm) Now today I can not even record..
damn I thought I had this licked...
I now get:
Aug 18 04:19:12 mythtv kernel: APIC error on CPU1: 08(08)
Aug 18 04:19:13 mythtv kernel: APIC error on CPU0: 04(04)
which is why everything is freaking out again.. well back to the drawing
board. (until I can actually buy a new motherboard)
Jim
