Hello,

From time to time i receive the messages:

in my kernel log. After that the computer freezes. What can I do to stop 
this?

I have al RH 7.2 with 2.4.20-pre2 kernel on 2 x PIII 1GHz (TYAN Tiger 
mainboard) machine.

Thanx you,

Greetings,

I got also the same problem on several Linux boxes:

Aug 14 16:35:30 linux0105 automount[777]: attempting to mount entry /data/prepayModel
Aug 14 16:35:30 linux0105 automount[777]: attempting to mount entry /data/commonFiles

Aug 14 16:40:53 linux0105 automount[9227]: expired /data/prepayModel

Some of the machines die, while other seems to recover from this error.

I got a mix of Tyan Thunder LE-T S2518 and 694D Pro (MS-6321) SMP motherboards. All of the running redhat 7.2, Linux XXXXX 2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown.

Apparently APIC IRQ is working well:

Looks like the IRQ are being distributed evenly between the processors:

Finally, this is my CPU info for this particular box:

This is my CPU info:

Different errors. BTW you ought to update the 2.4.7 boxes to the 7.2
errata kernel.

The long stream of 8/4 is something odder going on

I also receive a bunch of these errors on my ABIT BP6 motherboard.

Aug  5 20:43:00 hyperion kernel: APIC error on CPU0: 00(08)
Aug  5 20:43:00 hyperion kernel: APIC error on CPU1: 00(04)
Aug  5 21:41:44 hyperion kernel: APIC error on CPU1: 04(04)
Aug  6 21:53:29 hyperion kernel: APIC error on CPU1: 04(08)

Though this box has been solid even with these errors, it has never
crashed.

Linus also mentioned to me that if I didn't have any trouble I could
disregard these errors.
