Hi,
Got a testbed Proliant DL380G2, internal SmartArray 5i disabled, have
SmartArray 5300 with 6 disks.
Installed 6.1-REL last week, rebuilt to -STABLE three times since without a problem. However, when I try to
add various (random) applications the box locks up solid during "configure" or "make". Apps tested are
postfix, jdk15, OpenOffice-2.0 and more. When it hangs the only thing remaining is power cycling, no
keyboard access possible.
What puzzles me here is that now I installed -CURRENT from yesterday on same box without any other changes
and it works like charm, so far I'm through building close to 50 ports including kde with dependencies.
Next step I guess is to go back to RELENG and check again. Meanwhile, does anyone out there have an idea
where I should look? This box is going into production and I'm not brave enough to run -CURRENT...
Hi,
try to disable ACPI. It can be usefull for reading CPU temperature and fan
speeds, but has no real function on a server. It's mostly usefull for power
managment, supend and resume support. From the handbook:
Most system hangs are a result of lost interrupts or an interrupt storm.
Chipsets have a lot of problems based on how the BIOS configures interrupts
before boot, correctness of the APIC (MADT) table, and routing of the System
Control Interrupt (SCI).
Interrupt storms can be distinguished from lost interrupts by checking the
output of vmstat -i and looking at the line that has acpi0. If the counter is
increasing at more than a couple per second, you have an interrupt storm. If
the system appears hung, try breaking to DDB (CTRL+ALT+ESC on console) and
type show interrupts.
Your best hope when dealing with interrupt problems is to try disabling APIC
support with hint.apic.0.disabled="1" in loader.conf
Sorry, I should have mentioned that I tried both ways with same outcome.
