Hi everyone.
I'm getting kernel panics daily or even multiple times a day on a new
machine. When it's running everything works well, but over the last day
or two I've been getting multiple panics per day at seemingly random
times.
When the first panic happened, all I did was open up a new tab in my
graphical terminal. The second one I had VNC open to another FBSD box
and was maximizing the VNC window here to continue working on it. The
third one I was running a simple command via SSH on another machine (in
a graphical terminal). The fourth one was just pulling a website up in
my browser. The latest one was also working on another machine via SSH
in a graphical terminal. I had just switched terminal tabs and then it
panicked.
The CPU is nowhere near loaded at the times it panics, and since it
has happened several different times while doing different things each
time, I'm not exactly sure of one single event that triggers it. The
programs I have open when it panics are XChat, Opera or Firefox, XMMS,
a Terminal with some tabs, sometimes mplayer playing audio, and Claws
Mail. I've tested my RAM (brand new) with three passes of memtest86+
and there were zero errors. I have included some kgdb output, a dmesg,
and my kernel configuration.
This is the first real panicking problem I've ever experienced with
FreeBSD, so please let me know if there is any additional information I
can provide.
Thanks very much in advance.
