For some months now, our SUN 4/280 has been crashing with messages similar to this one: vmunix: nfsd: Data fault vmunix: kernel write fault at addr=0xffffeb7c, pme=0xe30015ba vmunix: Bus Error Reg 20<TIMEOUT> Other examples of the second line of the above have included: kernel write fault at addr=0xffffeddc, pme=0xe3001688 kernel read fault at addr=0xff121f38, pme=0xe30015d5 kernel read fault at addr=0xff651e2c, pme=0xe30017f7 kernel read fault at addr=0xff664d8a, pme=0xe300167e kernel write fault at addr=0xff0aa19a, pme=0xe3001788 kernel read fault at addr=0xff0aa198, pme=0xe3001788 kernel read fault at addr=0xffffe858, pme=0xe3001551 There have been more. The fact the the values for ``pme'' are so similar is suspicious. I've suspected one of our memory boards, but can't translate the ``pme'' value into anything reasonable. Can anyone tell me what ``addr'' and ``pme'' refer to? Is this a disk or memory error that is causing the crashes? I will gladly RTFM if someone can tell me which one, where. Thanks in advance, George Nassiopoulos nassio@cfa.harvard.edu
