Hi all

I'm using FreeBSD 6.2-RELEASE on Intel P4
3.0GHz,
512MB Ram computer.

Its very irritatingly hangs very frequently,
more
than
10 times a day. Do others find FreeBSD
6.2-RELEASE
always hangs? I simply cannot use it for any
serious
use, not even to send a mail, other than
browsing
web.

I find it mostly when I try to move the
mouse it
hangs. Upward and downward cursor keys press
and
hold
also hangs, but not always. These may be
just
coincidental. How do I find why it hangs?
How is
the
stability of the upcoming 7.0?

Best Regards

I'm sure I'm not alone in this, but I'm
running
several 6.2-RELEASE-p8
boxes (servers and laptop workstations) for
several
months now without a
single lock-up. I'd first look into hardware,
testing memory, testing
the power supply, and checking CPU/chipset
temperatures as they have
often contributed to problems similar to what
you
are describing. 6.2
has been working extremely well for me with no
stability issues that
weren't related to hardware problems.



Thanks for all the replies.

It may be a hardware issue. This is a more than
four
year old computer. Btw, I forgot to mention this
is
not a server, its running KDE, trying to use as
a
desktop.

Any one of the hangs do not develop any core
dump or
/var/crash/kernel.0 or /var/crash/vmcore.0. Just
the
cursor disappear and keyboard does not respond.
Only
switch off and on can bring the machine up.

Are there any hardware analyzing software that I
can
run on FreeBSD, so that I could narrow down the
cause?

Can you verify that the machine is actually dead?
Do you have another
machine that you can hook up either to a serial
console, or ssh into the
dead box? Weird X symptoms could lead to an
unresponsive keyboard, with
the machine running just fine underneath X.

Just to re-enforce this, I have a colleague who is
seeing this on his
Radeon-based Lenovo T43 (m300). The display blanks
and cannot be
resurrected, even CTRL-ALT-BS does not help, but the
system is alive.

Oddly, I also have a Lenovo T43 based system and it
has never shown this
problem. It might be something in your xorg setup
that is triggering it.

If your system is a Radeon, you might try booting
with no xorg.conf
file. I have found that worked well for my system.
Other possibilities
include hw.acpi.reset_video=1 (sysctl.conf) and
acpi_video_load="YES"
(loader.conf).

I would like to figure out why my system has no
issues while others
go off to never-never land.


Mine is also an ATI Radeon card:
ATI Technologies Inc RV280 [Radeon 9200 PRO] rev 1
Chipset ATI Radeon 9200PRO 5960 (AGP)

I cannot ssh to the machine while its freezes. It says
'no route to host'. That is, the machine is completely
dead.

The other thing is, FreeBSD installer has not
installed an xorg.conf.

I have created an xorg.conf using Xorg -configure and
moved to /etc/X11/. Adjusted the HorizSync and
VertRefresh to match the monitor, driver I used "ati",
added Modes and an DRI section with Mode 0666.

If it crashes again I'll let the list know.
