Yes, thank you for your suggestion on how to debug the driver via mbuf dumps. I can only hope I'm able to do that. :-) Its been many moons since I did any kernal debugging. Perhaps Chis at Marconi can shed some light on microcode revs too. Perhaps I'm using downloadable microcode that's not the right revision. I know people have said 3.5 FreeBSD runs the ATM PCA200e well. Perhaps I should just move back to that OS.. Forward sounds better though. ----- Original Message ----- From: "Joe Thomas" <joe_thomas@cnt.com> To: "'Alex Huppenthal'" <alex@aspenworks.com>; "Archinaco, Chris" <Chris.Archinaco@marconi.com> Cc: <freebsd-atm@FreeBSD.ORG> Sent: Friday, April 06, 2001 9:49 AM Subject: RE: SR100069960 - Linux resources > > The API for the 200E line of adapters is available as > ftp://ftp.fore.com/pub/docs/port/aali.pdf.
