Default root waiting for

Hi!

My system: FreeBSD 8.2-RELEASE-p3 #0: Tue Sep 27 18:07:27 UTC 2011
/etc/fstab looks like:
Code:
  Device                Mountpoint      FStype  Options         Dump    Pass#
 /dev/ad0s1b             none            swap    sw              0       0

 /dev/acd0               /cdrom          cd9660  ro,noauto       0       0
I ran memtest and everything was O.K.
I have a HP Business Inkjet 3000 printer which is connected through router but
I did also try to connect with USB and from this time (I think) I have"
root waiting to: usbus4".

dmesg shows:

Does the system continue to boot when you remove the USB device (printer in this case)?, I believe this is a known issue, but did not investigate at this point, the more important (and probably unrelated) issue seems:

My first hunch would be a hardware issue.

You mentioned you ran memtest, how long did you run memtest? Make sure you run it for *at least* several hours. And if possible at least a day.
Detecting memory issues is not as easy at it might look at first glance (See the README in the memtest86+ source package for details).

Another possibility is overheating, especially if the problem occurs when compiling stuff.
Getting the CPU/system temperature varies a bit from system to system, take a look at coretemp(4) for Intel systems or amdtemp(4) for AMD systems.

Posting your full dmesg may also help, so we know what system/cpu/chipset/etc. you're using.

.
I ran memtest about 12 hours but it was memtest not memtest86+. I will run memtest86+ again.

I had printer connected with usb just ten minutes and because didn't work correct I installed cups and connect printer to the broadband router and it works good. I don't have a problem to boot computer.
Today I updated gcc 4.5 and gcc 4.6 and was nothing wrong. Later try to update kdegames4 and when I came back computer was frozen. But after next try it was success and it works still.
Here is dmesg (I am charging my phone now):

There's nothing wrong with memtest86, memtest86+ has a few new features and support for newer chipsets/CPU's (Which you don't have), but it's not fundamentally "better". No need to run it again. I just wanted to make sure you didn't just run memtest for something like 15 minutes (Which is what many people do)

You seem to have a Pentium D CPU, and they do tend to get hot.
I don't quite remember how to get the CPU Temperature on the P4, you can try:
# sysctl -a | grep C\$

And see if that turns up anything.

You can test your temperature by starting in one xterm a "temperature monitor script":
Code:
#!/bin/sh
while 1; do
  clear
  sysctl dev.cpu.0.temperature dev.cpu.1.temperature | tee temp.log
  sleep 1
done
... Assuming you get your temperature from dev.cpu.?.temperature ...

Then load both cores 100%, the easiest way is to use Python, do this twice:
# python -c '9999999999999999999999**9999999999999999999999999 9'

Leave it running for 20 minutes, if the system doesn't reboot and the temperature stays reasonable (<~80°C) you probably don't have a heating problem ...

Thank you very much, Carpetsmoker. I will try today. I need to check the fan on processor. Computer is old about eleven years but FreeBSD works excellent .

Mitja

Thank you very much for the help. I did everything as you wrote and I didn't find a problem and computer still running (about one week) and I compile gcc, firefox... and there were no problems.
I think that is problem when I restart computer. Sometimes I have a problems as I describe but after few reboots is okay.. And as I wrote box is old about eleven years and I start thinking about new one .
