I have an Asterisk system with Fedora Core 4.0, kernel
2.6.14-1.1637. It sometimes locks up with heavy load (e.g., lots
of HDLC messages). This requires a hard reboot.
I saw some other reports of hard lockups under load. I have
disabled as much as possible in the BIOS and as much as possible in the
modules (e.g., removing USB, turning off lots of not-needed services,
etc.) Could this be a Fedora problem, zaptel problem, or
other? This is reproducible on several systems. I am using
ZAPTEL <a href="http://1.0.9.2">1.0.9.2</a>. My next test is to try the 1644
kernel update.<br>
