 Did you try and incorporate patches available from the PAO
 web site for this driver? They have put some effort into making the
 device more reliable.

 Are you still using FreeBSD 2.2.x? Did an upgrade to 2.2.8 solve your
 problem?

 Nope...  My solution  was  to reduce  MTU  to 900  --  seems to  improve
 performance and definetly improves the stability.

 I went straight to 3.2-STABLE and the card hung within a couple of hours.
 
 
 	ifconfig ep0 down
 	ifconfig ep0 up
 
 made it  work again, as it  did before. I  then changed the MTU  and the
 problem is gone. Will PAO work with the 3.2 stable?

 Can you mail the relevant parts of dmesg.
 
 So we can see the make and model of the card.

 There is a PAO for 3.3 even.

 Have you tried reversing the cards?  It would be interesting to see if the ep 
 card
 fails as frequently when connected to the cable modem instead of the local net.

 This is the same bug as PR kern/9537
 
 I have more info - I have the exact same problem on a Compaq 386/33DX Deskpro
 with a total of 4 3c579 EISA cards using the ep driver and set up as a router, 
 running
 FreeBSD 3.4  This system had been previously running for 3 years continuously 
 as
 a mailserver, running an SMC8013 card, with no problems, so I feel that it's 
 most
 likely not the system hardware.  I also get the "no buffer space available" 
 error
 message listed in PR kern/9537  On my router the ep card that is connected to 
 the
 busier network generally fails.  (fortunately the non-busy side faces the 
 Internet so I can get
 into the machine and shake the other ep interface awake.)  This would almost 
 indicate
 a problem in the transmit logic, as the majority of dataflow through this 
 router is from
 the Internet side (that doesn't go offline) to the busy network side.  However, 
 both cards
 have failed from time to time.  Although, PR kern/9537 and PR kern/8861 also 
 deal with
 outbound data flow through the card.
 
 While the PAO suggestion is a good one, I have checked through the diffs on the 
 most
 current version of PAO for FreeBSD 3.4 and there is nothing in them to suggest 
 any
 corrections for this problem.  The corrections mainly deal with hot insertion. 
  This may
 be because some ep corrections originating in ep have already been entered into 
 the
 FreeBSD source tree.

 I've seen this same problem with a number of different cards, using either
 ep, xl or fxp drivers running on FreeBSD 4.1, 4.2, 4.3 and 4.4. I'm using
 the machine as a gateway and firewall for my cable modem connection which is
 managed by the BPALogin daemon. I've given up trying to fix it so I've
 currently got a cron entry to bounce the card every hour which seems to work
 well enough.

 Stephen Graham.

 I am also seeing this problem with a 3Com Etherlink III (3C589D) I'll =
 start using the work-around of toggling the card in crontab. Are there =
 any patches that I might want to try?
 
 This is on FreeBSD 4.8-STABLE, cvsupped as of monday 28 april 2003. =

 So what? The bug was reported in 1998. The chance, that I still have
 the same hardware (a 486) is about as good, as that for the driver's
 maintainer, or any random person.
 
 No, I do not have neither that computer, nor that card any more. And did
 not for at least 5 years. I'm also aware of a great number of changes in
 =46reeBSD, which would make that PR obsolete.
 
 And yes, I'm a little bitter about the bug-response latency...
 
 I know, you are trying to clean the PRs up, and appreciate that.
 
 =46or all I care, you can close the PR.
