This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig9B9CEF8119C69A8A958451C9 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable I have a strange problem with a PRO/1000 EB NIC (card=3D0x109615d9 chip=3D0x10968086) built into the motherboard (5000X chipset) that manife= sts itself in NIC stopping responding to ARP packets requesting its address while in Windows XP, after being rebooted from FreeBSD (dual-boot). The sequence is: ** cold boot (after the power has been disconnected from the PSU) into WinXP: NIC works on WinXP ** reboot into FreeBSD: NIC works ** reboot into WinXP: NIC doesn't respond to ARP ** reboot into FreeBSD: NIC works ** reboot into WinXP: NIC doesn't respond to ARP ** cold boot into WinXP: NIC starts working again I found the cold boot resolution by searching the net, apparently it's a semi-known problem: http://www.supermicro.com/support/faqs/faq.cfm?faq=3D7837 - my motherboard isn't the one mentioned on this page but they share the same chipset (Intel 5000X - this is a Xeon-based workstation). I confirmed that it's an ARP issue by two things: - computers with a large ARP timeout can access the machine while the ARP entry is cached at their side - connecting a laptop via crossover to the machine and using arping clearly shows that ARP is responding until reboot from FreeBSD to WinXP. This is a workstation for developing and testing cross-platform software so rebooting between operating systems is common. Any ideas? Software involved: - FreeBSD 8-CURRENT amd64 - WinXP SP3 i386 - For WinXP, tried both the drivers from the motherboard maker (12.4) and the newest available on Intel's web site (13.2.8) dmesg, etc. are available. --------------enig9B9CEF8119C69A8A958451C9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFI3NsnldnAQVacBcgRAgBvAKDWtiZqtqWxCzi5ThRsQyycA8nCDQCfR2u+ MEQKOA/tapwQRGiHyvSInnU= =YVhd -----END PGP SIGNATURE----- --------------enig9B9CEF8119C69A8A958451C9--
