Hello, I have i computer figuring as a router, on which i have 3 nics installed. 2 working flawlessy, one is producing errors: NETDEV WATCHDOG: eth1: transmit timed out eth1: Transmit timeout, status 0d 0004 c07f media 00. eth1: Tx queue start entry 4 dirty entry 0. eth1: Tx descriptor 0 is 0008a0e5. (queue head) eth1: Tx descriptor 1 is 0008a0de. eth1: Tx descriptor 2 is 0008a0e5. eth1: Tx descriptor 3 is 0008a0de. eth1: link up, 100Mbps, full-duplex, lpa 0x41E1 i was googling, just finding something about interrupts. I changed the interrupt of eth1 to 9 (acpi), no help. can anybody figure out or has some hints that i could try? my /proc/interrupts: [root@trinity proc]# more interrupts CPU0 0: 593132 XT-PIC timer 1: 952 XT-PIC i8042 2: 0 XT-PIC cascade 5: 1 XT-PIC CS4231 6: 5 XT-PIC floppy 7: 1 XT-PIC parport0 8: 1 XT-PIC rtc 9: 0 XT-PIC acpi 10: 1 XT-PIC eth1 11: 12470 XT-PIC uhci_hcd:usb1, eth0, eth2 12: 15173 XT-PIC i8042 14: 13840 XT-PIC ide0 15: 36367 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 so, i get some sun now, otherwise i get eyes like gollum :) Thanks, Roger Setting acpi=off in the kernel-bootline in /etc/grub.conf did the trick. its working now.
