[Fwd: Re: [LARTC] ssh and cs LAG]

[Hariett Jones]

Got some solutions myself.

LAG is caused by :
NETDEV WATCHDOG eth0 timeout

this is caused bacause of problems with rtl8139 network card in kernel 2.6.x

Solutions :
1.add in lilo.conf : append="noapic"
2.turn apic off in bios
3.if u have 2 rtl8139 cards, then exchange one with some other card type 
(chipset)

btw. all above was found in various polish forums, but none has worked 
for me. im switching kernel back to 2.4.22, and will report later .

Switching back to older kernel won't do much.
I've had this problem much earlier when using two NICs of the same type.
I couldn't figure out why, but there ARE problems is many ways when
using two cards of the same type. I had problems with sharing, with
routing, etc. etc.
Best solution is to use different NICs... don't ask me why... I just
found out that this will solve the problems...

It's probably the machine.  I have three rtl8139 based cards in a box and it's 
been working flawlessly for six months.  I've used 2.4 series kernels and 2.6 
series kernels on the box in question.

Hariett,

Switching to the 2.4 kernel is not an option as this is a production server.

The machine has a dual Intel PRO/1000 NIC.

The machine usies grub, not lilo, but that doesn't really matter.  Not 
sure if APIC is an issue or not.

Thanks for your help.

Mike

I had to unselect SMP in kernel config to get my rtl8139 + PCI modem to 
work with 2.6.8.1

We had no problems with smp on 2.6.8.3, and since this cpu supports 
hyperthreading we enjoy a *big* power boost using smp.  :)

I think it's this box(via p200) + rtl8139 that's the problem - it's 
always been a bit flakey. I have the same card in a PII350 intel440bx 
and it has always been OK.
