eth0: Too much work at interrupt, IntrStatus=0x0001
Hi,
I'm having this error in dmesg, i'm using debian (woody) with kernel 2.4.25 and the driver compiled inside the kernel (8139too), and i'm using vmware with bridged network.
#lspci -v (just posting the ones with the same IRQ)

I discovered I was getting this problem because my NIC connection was not good. Maybe a few pins were touching but not all of them?? Who knows. But some good old fashioned fiddling did it.
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!
