2.4.27 suddenly hangs

2.4.27 suddenly hangs

[zergio]

Hello, all!
I‘m not sure that the below problem is kernel related, however, I think, 
this mailing list is the best place to start. I've got 2x1.8 Xeon on 
Intel SE7500CW2 motherboard with Intel SCSI RAID (GDT driver). The 
system powered by Red Hat Linux 7.3 with custom kernel version 2.4.27.
Occasionally, the system just hangs, without giving any error messages 
to syslog or any panic-like messages to the screen. No response to ping. 
Usually it happens on weekends in early hours, but not at particular 
time and day, when users’ activity is minimal. Couple of times the last 
few messages before, the hang had strange timestamps. It seems like the 
system time entered a TIME LOOP within a period of 1 second.
Nov 6 05:37:31 service dhcpd: Message...
Nov 6 05:37:32 service named: Message...
Nov 6 05:37:31 service named: Message...
Almost all the time last messages came from different services, except 
three times, when mgetty was the last. I'd updated mgetty, pppd, kernel 
(from 2.4.20), BIOS, dhcpd etc., however, the problem remains.
Can anyone tell me, how I can detect, what application or hardware cause 
such a problem.
Any ideas would be appreciated.
Thank you in advance

I have a similar problem at the moment, i have setup my box with gentoo 
and now i get hardlocks from time to time (time < 1.5 days), happens 
with and without x, kernel 2.4.27 untainted, with apic on and off, acpi 
on and off, apm on and off...

@zergio: Can you tell me if it only happened with 2.4.27?

The system is really stuck when it crashes. My wireless keyboard has a 
led to indicate traffic, an when system hangs, not even the led would 
blink, it just stays in either on or off state (its normaly off). No 
disk activity, mouse is locked, display remains unchanged (x.org nv or 
plain (non-fbdev) console). Havent tried so far to reach the box over 
network, but is suspect it will not work.

@developers:
Maybe thats a hint, could it be that a broken keyboard induces such 
behaviour?

Im going to change kernel to 2.4.24 (had uptimes > 14 days with it) and 
see if it helps.

As far as i can see, nothing was written to the logs, no messages, it 
just peacefully dies...

No, it had happened with 2.4.20 kernel.

In my case it has happened with and without keyboard and with keyboard 
connected to D-Link KVM Switch

There is no strict period of time. Some time server up for couple of 
month. Recently the issue occured twice within 7 days.
It've happened 7 time during last half a year or so.

Go into the bios and disable USB keyboard support and USB storage/boot
off USB devices (however they phrase this in your BIOS). That *may*
help. It does for some similar reports.
