Subject: RE: 2.6.35-rc3 BUG: unable to handle kernel paging request at 0000000000004008

Greetings folks;

I finally got amanda running on an mdv-22010-x64 system last night & left it 
running when I went to bed as it had about 64Gb to backup.

Up just after 6ish, the system wasn't very responsive & while looking 
around, both kmail and x eventually hung.  I could see by the drive led that 
amanda was still working so I went back to bed.  But I'd found a couple of 
BUG entries in messages so here they are:
