Well this is novel. I'd be suspecting a hardware problem. Are you sure
the power supply isn't overloaded, or in need of replacement?

Subject: [Bugme-new] [Bug 3765] New: Network link down, when writting to sata
disk AND network in use
http://bugme.osdl.org/show_bug.cgi?id=3765
Summary: Network link down, when writting to sata disk AND
network in use
Kernel Version: linux-kernel 2.6.9
Status: NEW
Severity: high
Owner: other_other@xxxxxxxxxxxxxxxxxxxx
Submitter: bugtracker@xxxxxxxxxxxx
Distribution: Gentoo
Hardware Environment:
P4 2.66ghz
Motherboard: ASUS P4PE (with onboard lan)
Promise Sata150 TX4 PCI (sata expansion card)
Software Environment:
Kernel 2.6.9
- onboard LAN: driver in use
- "Broadcom 4400 ethernet support" compiled into kernel
- Promise Sata150 TX4 PCI (sata expansion card)
- Driver "Promise SATA TX2/TX4 support" compiled into kernel
- 200GB Western Digital SATA drive attached to PCI sata card
Problem Description:
If data is being copied to the SATA drive (eg from another DISK which is on
motherboard IDE controller) AND I start a network data transfer where data is
goung through the Broadcom lan the following occurs (from kernel log)
Nov 18 11:43:10 synapse b44: eth0: Link is down.
Nov 18 11:43:15 synapse b44: eth0: Link is up at 100 Mbps, full duplex.
Nov 18 11:43:15 synapse b44: eth0: Flow control is on for TX and on for RX.
Nov 18 11:43:19 synapse b44: eth0: Link is down.
Nov 18 11:43:21 synapse b44: eth0: Link is up at 100 Mbps, full duplex.
Link keeps going up and down, as long as there's data movment from the SATA
drive, and a network movement (network download doesn't have to be saving to the
sata drive)
I've disabled APCI, problem persits.
Steps to reproduce:
1. copy data to Sata drive CONNECTED to PCI controller
2. Download file from network via onboard LAN, doesn't matter which drive you
save it
3. Onboards lan "link" goes up and down, causing disruption to network useage.
