when using nfs alot i occasionally get a message like:
eth0 Too much work at Interrupt. IntrStatus=0x0040
what's wrong? it only happens on one machine in my network and it's not the server

if you have other nfs clients, then you could compare the nfs options in
/etc/fstab. Also I have seen this message on google where there are conflicts with the audio driver. sorry I dont have more information, hope this helps.

Hello. I fixed the problem. One of my computers, which is the router, had two (rtl 8139 chip) ethernet cards. They were using the same driver: 8139too.o

The error message: Too much work at interrupt, IntrStatus=0
, is coming from the driver 8139too

After a quick look at the source code, you can see that one of the functions can only be executed 20 times in a short time.

static int max_interrupt_work = 20;
int boguscnt = max_interrupt_work;
......
boguscnt--; // REMOVE -1 FROM BOGUSCNT
} while (boguscnt > 0);

if (boguscnt <= 0) {
printk (KERN_WARNING "%s: Too much work at interrupt, "
"IntrStatus=0x%4.4x.\n", dev->name, status);
......

Maybe the driver is wrongly coded.
I replaced one of the two cards. I have put a rtl 8029 chip card. So they aren't using the same driver.
Now everything work fine, no more error messages. And now I can upload faster than in the past. I was unable to upload faster than 2 kbytes/s when I was having the error message. Now it's at 103kbytes/s!

Sorry for my english, I speak french =)
