Subjecteth0: Interrupted while interrupts are masked!
Greets.

I've been receiving these messages for quite a long time now under my SMP
system when high levels of network activity exist.

The exact messages are:

eth0: Interrupted while interrupts are masked! isr=0x0 imr=0x0.

The isr= and imr= values never alter.

I was told that these messages were immaterial since I was using egcs 1.1.
Well, after some free time finally, I've made the following tests:


kernel compiler smp? problem?
---------------------------------------------
2.1.122 egcs y yes
2.1.122 gcc2.7.2.3 y yes
2.1.122 egcs n no
2.1.122 gcc2.7.2.3 n no
2.1.125 egcs y yes
2.1.125 gcc2.7.2.3 y yes
2.1.125 egcs n no
2.1.125 gcc2.7.2.3 n no

So, it seems fairly certain that SMP is the cause of this, not egcs (as
was alluded to). Triggering this effect is trivial: copying a file across
NFS or 'telnet server chargen' will reproduce it 100% of the time.

System information is available at

The really sad part is that yesterday I _absolutely had to_ copy a large
file across NFS. The ONLY way I was able to accomplish it was to recompile
the NFS server as UP, reboot, copy, reboot back into SMP.

I think this should be looked into before we proclaim 2.2.

G'day!
