Somehow I knew this was going to happen. I just got done upgrading one of my Indigo2s to IRIX 6.5.4, with am-utils 6.0 for NFS automounting. IRIX 6.5.4 supports NFS v3 and TCP. I tried cd'ing to a directory served on a FreeBSD 3.2-RELEASE system which happens to have the build tree for the Alteon Tigon firmware (that's where I compiled the last firmware image for the Tigon driver). I did a 'du' and after a short while, it exploded with the following messages: mbuf siz=33524 panic: Bad nfs svc reply Inspecting a crash dump showed that the mbuf chain was trashed. The same thing happens with a 4.0-current snapshot from the 15th: this time I just manually mounted /usr from the FreeBSD server under /mnt on the SGI and did cd /mnt; du. Pow: died right away. The FreeBSD 3.2-RELEASE host has a 3Com 3c509 card. The 4.0-CURRENT host has a 3Com 3c900-COMBO PCI card. Each uses different drivers and networking works fine otherwise, so I'm pretty sure the problem is in NFS somewhere and not in the drivers. This doesn't happen when using UDP. Given that I can reproduce this on demand, I should be able to debug it eventually, but hints in the right direction would be useful. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
