intermittent network issues
Hi Everyone,
I upgraded my machine a couple of days ago to an asus p4p800 motherboard
(http://www.asus.com/prog/spec.asp?m=P4P800&langs=01) with on board sound
and lan (not that I particularly wanted anything on board).
Since the upgrade, I have been having numerous problems with the network.
I used to have two network cards in the machine - an rtl8139 chip card and
a hp card - J2585B forw which I used the hp100 module.
The motherboard has the 3com gigabit lan for which I use the module
downloaded from the asus site(3com2000).
Right now, lspci shows devices as unknown included the host controller
which I believe is springdale. When everything was freshly installed, it
refused to recognise just one of the 5 installed pci cards. after
shuffling them around a bit, it eventually recognised the hp card, sound
card, tv card and scsi card. However, it never detected the rtl card apart
from saying that it was a network card and it didnt show up as a network
interface either.
The hp100 did show up as a network interface and worked fine for a while -
all day yesterday in fact. However, this morning, it decided to stop
working. After fumbling around for a while, I got the 3com card working -
dont know why it decided to work but I insmodded and it just worked.
However, after working for a few hours, that stopped working as well after
showing a few errors along the lines of hardware failure and unexpected
irq error.
The hp100 now works intermittently again as in it drop a few packets now
and again and regularly (perhaps every 20seconds or so) just stops working
for about half a minute or something.
When pinging another machine on the network, after around 500 packets, i
get 60% packet loss. The hub flashes for each packet sent out but doesnt
seem to flash back.
There are no problems pinging between other machines on the network and I
have the same problem pinging from another machine to this one.
I very much hope that someone can point me in the correct direction to
solving this very annoying problem which is starting really depress me.
I should mention that I have also tried switching the cables and upgrading
the kernel to 2.4.21 from 2.4.20 to no avail.
Thanks,
Shri
