Which phy is used by your board? Could you enable dprintk (near line 115) and reload the driver?



I've enabled dprintk and captured *.debug syslog output from a normal
boot. Here is the result:

http://cyberelk.net/tim/tmp/forcedeth-debug



The log is very odd - why are there two lines with

forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.28.

Did you rmmod/insmod the driver twice?


Could you manually insmod the driver, wait for two seconds and then call ifup? The new driver
- resets the phy during _probe. The result is no link for a few seconds, until autonegotiation has completed.
- check if there is a link during _open(). If there is a link, it's used. If there is no link, then it relies on the link irq to detect it.

I frequently see the "no link" messages during ifup, but on my system the driver recovers as soon as the autonegotiation is completed. Perhaps I must add a link handling timer that polls for link changes.

If a delay before ifup is not enough: manually call nv_link_irq even if NVREG_IRQ_LINK is not set. If this is not enough: comment out the NVREG_MIISTAT_LINKCHANGE test in nv_link_irq.
