[eepro100-bug] Performance problems ?

[Kuht, Mike (M.D.)]

Hi,

Has anyone else suffered performance problems with Intel EtherExpress Pro100
as follows ? 

I've got a DELL 4300 with Dual Pentium CPU's running Linux 2.2.13 SMP
Kernel. Originally I was getting the kernel message after periods of heavy
network load :

Jul 14 09:26:42 jwsaac14 kernel: eth0: Transmit timed out: status 7048  0000
at 12273905/12273919 command 000ca000.

Jul 14 09:26:42 jwsaac14 kernel: eth0: Trying to restart the transmitter...

So I've upgraded to the latest version of the eepro100 driver (v1.10) and
got the message :

Jul 21 10:56:51 jwsaac14 kernel: eth0: IRQ 20 is physically blocked! Failing
back to low-rate polling.

I then saw a message suggesting the "noapic" setting & lilo'ing, so I've
tried that for fun and although the Ethernet card now uses an interrupt <15
I still get the same problem :

Jul 29 21:06:04 jwsaac14 kernel: eth0: IRQ 14 is physically blocked! Failing
back to low-rate polling.

Ideas anyone ???

TIA
