F20: message from syslogd and soft lockup/kernel bug

[Ranjan Maitra]

Hi Gary,

Thanks! I also have updated my BIOS (as mentioned in a subsequent post) but I have continued to have frequent error messages and lockups even with the mainline vanilla kernel. I have filed bug reports on both kernel.org and fedora -- hopefully it will be fixed soon.

Btw, what does running memtest for 24 hours mean? What do I have to do? 

Many thanks and best wishes,
Ranjan
