Totally Out of Ideas on Fixing Network Bug

[Null Ack]

Hi Daniel. Thank you very much for your help on this problem.

I've trawled through all the logs, and I previously provided a relevant
section of the kernel log to the bug report:

Jun 21 04:34:46 ppp kernel: [ 5493.104588] NETDEV WATCHDOG: eth0: transmit
timed out
Jun 21 04:34:46 ppp kernel: [ 5493.104738] eth0: Transmit timed out, status
0003, PHY status 786d, resetting...
Jun 21 04:34:46 ppp kernel: [ 5493.105384] eth0: link up, 100Mbps,
full-duplex, lpa 0x45E1

Which then sets into a repeating pattern:

Jun 21 05:05:02 ppp kernel: [ 7308.203455] NETDEV WATCHDOG: eth0: transmit
timed out
Jun 21 05:05:02 ppp kernel: [ 7308.203606] eth0: Transmit timed out, status

Jun 21 05:05:02 ppp kernel: [ 7308.204254] eth0: link up, 100Mbps,
full-duplex, lpa 0x45E1
Jun 21 05:35:16 ppp kernel: [ 9121.303308] NETDEV WATCHDOG: eth0: transmit
timed out
Jun 21 05:35:16 ppp kernel: [ 9121.303457] eth0: Transmit timed out, status
1003, PHY status 786d, resetting...
Jun 21 05:35:16 ppp kernel: [ 9121.304106] eth0: link up, 100Mbps,
full-duplex, lpa 0x45E1

This occurs shortly before the first occurance in the kernel log:

with the "irqpoll" option)

Jun 21 04:29:46 ppp kernel: [ 5193.747710] Disabling IRQ #23

As I said in the bug report comments, I am not using an Intel nic. My module
is the via-rhine. as per lspci

00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev
7c)
    Subsystem: ASUSTeK Computer Inc. Unknown device 80ed
    Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr-
Stepping- SERR+ FastB2B-
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
    Latency: 64 (750ns min, 2000ns max), Cache Line Size: 64 bytes
    Interrupt: pin A routed to IRQ 23
    Region 0: I/O ports at 9400 [size=256]
    Region 1: Memory at dffff800 (32-bit, non-prefetchable) [size=256]
    Capabilities: <access denied>

Therefore:

ppp at ppp:~$ sudo rmmod via-rhine
ppp at ppp:~$ sudo modprobe via-rhine

I like the idea of a workaround :) I had one, where I manually added the
default gateway but that failed after another suggestion of hacking up the
aspci conf so I need to go back to the original conf to retest.

Will test your suggestions, thanks
