btlan4: Hardware Reset

[Verónica Muñoz Segovia]

I'm having the follow message constantly on syslog.log:

btlan4: Hardware Reset Started on 8/12/1/0....This will take approximately 11 seconds
btlan4: NOTE: 100Base-Tx Full-Duplex started at 8/12/1/0

How can I fix it?

For some reason, your btlan4 card's link to the hub/switch keeps getting dropped and restarted - you might want to examine your hub/switch for any weird behavior - try another port and see if it continues.

This message shows up everytime there is a link established with the hub/switch.

Veronica,

If the solution provided by Kofi, doesn't help try installing one of the latest HSC 100BT patch, see below.
In the patch description of patch PHNE_19946, which has been replaced by patch PHNE_22216, the following is described:
After cable is re-connected the driver
detects cable connection and issues an internal
reset command. The internal loop back fails during reset. This causes an endless loop of resets being done to recover from this error. The internal loop back fails due to Rx interrupt not being delivered to the driver during reset.
Resolution:
The driver recovers from this error condition in dma timeout routine by checking the owner bit for the descriptor and calls offline isr handling routine if driver owns the descriptor.

I check my hub and looks fine, I'll try the patch option, unfortunly I can't reboot now the server. Thanks for the responses.

Veronica, you can also try turning off autonegotiation, both on the switch and the card. There is a whitepaper athttp://docs.hp.com/hpux/onlinedocs/netcom/autonegotiation.pdf
that details the problems some 100BaseT cards have with autonegotiation. It also explains how to turn it off. (no reboot required)
