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 http://neko.binary9.net/scripts/sysinfo
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!
