Something(s) Wrong

Thu Sep 13 23:46:48 UTC 2007

Performed the memory test and there were no errors. The result of free is"

bob at java:~$ free
                      total           used            free     shared
buffers     cached
Mem:       2059460    1837756      221704              0      40492
514572
-/+ buffers/cache:     1282692      776768
Swap:      6032368                0    6032368

I can't see any problems with the memory and can't see why dmesg would
complain as it did. After rebooting, however, the error grep dmesg only had
one error as follows:

bob at java:~$ sudo dmesg | grep error
[  146.107557] powertweakd[7223]: segfault at 0000000000000006 rip
00002b498d401620 rsp 00007fff1de80488 error 4

There were no hald problems either.
Thank you.
Bob
