I posted this a while back but didn't get much of an answer beyond (use a 3com card instead). I have a bunch of Dell 1550's with on board Intel NIC's. I received the following messages on the console (below), any attempt to ping results in the message "No buffer space available." May 14 16:03:12 web5 /kernel: fxp0: DMA timeout May 14 16:03:12 web5 /kernel: fxp0: DMA timeout May 14 16:03:12 web5 /kernel: fxp0: SCB timeout: 0x10 0x0 0x80 0x0 May 14 16:03:12 web5 /kernel: fxp0: DMA timeout The first box this happened on I chalked it up to a bad NIC or PCI bridge and had Dell replace the motherboard, the problem hasn't occured since. A week after the same thing happend on another box. This, combined with a number of other posts about these fxp problems makes me suspect this is an OS level problem rather than hardware. This occured under a cvsup'd version of 4.5-STABLE, I then upgraded to 4.6-PRERELEASE as of a few days ago and the problem persisted. The box will be up anywhere from 15min to an hour before the above messages appear and send it out of service. pciconf -l: chip0@pci0:0:0: class=0x060000 card=0x00000000 chip=0x00081166 rev=0x23 hdr=0x00 chip1@pci0:0:1: class=0x060000 card=0x00000000 chip=0x00081166 rev=0x01 hdr=0x00 chip2@pci0:0:2: class=0x060000 card=0x00000000 chip=0x00061166 rev=0x01 hdr=0x00 chip3@pci0:0:3: class=0x060000 card=0x00000000 chip=0x00061166 rev=0x01 hdr=0x00 fxp0@pci0:1:0: class=0x020000 card=0x00da1028 chip=0x12298086 rev=0x08 hdr=0x00 fxp1@pci0:2:0: class=0x020000 card=0x00da1028 chip=0x12298086 rev=0x08 hdr=0x00 none0@pci0:3:0: class=0x030000 card=0x00df1028 chip=0x47521002 rev=0x27 hdr=0x00 isab0@pci0:15:0: class=0x060100 card=0x02001166 chip=0x02001166 rev=0x50 hdr=0x00 atapci0@pci0:15:1: class=0x01018a card=0x00000000 chip=0x02111166 rev=0x00 hdr=0x00 ahc0@pci2:5:0: class=0x010000 card=0x00df1028 chip=0x00cf9005 rev=0x01 hdr=0x00 ahc1@pci2:5:1: class=0x010000 card=0x00df1028 chip=0x00cf9005 rev=0x01 hdr=0x00 It looks like quite a few people are having similiar problems with the fxp cards, is anyone close to a fix? Please let me know if there's anything I can do to assist in debugging this issue. Thanks, Paul P.S. The motherboard is SMP capable but only has one processor installed, SMP is turned off in the kernel configuration. Disks are on an adaptec aic7899 SCSI controller. Server is an NFS client using TCP mounts. Network is 100mbps, switched, fxp0 properly autonegiotates to 100mbps/full duplex.
