-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am resending this the third time since my previous messages didn't seem to go through. I was persuaded to report this on freebsd-current. I just installed 7.0-current as of May 3 on my new computer that comes with an on-board Marvell Yukon Gigabit Ethernet. Every now and then if the network throughput comes near several hundred kbytes, I get the msk0 watchdog timeout messages: kernel: msk0: watchdog timeout msk0: watchdog timeout (missed Tx interrupts) -- recovering Although it says recovering, the interface never comes back alive. Sometimes doing a kldunload / kldload if_msk can bring the interface back, but sometimes it is helpless with the following message when I reload the kernel module: kernel: mskc0: <Marvell Yukon 88E8053 Gigabit Ethernet> port 0xb000-0xb0ff mem 0xf9000000-0xf9003fff irq 16 at device 0.0 on pci4 kernel: msk0: <Marvell Technology Group Ltd. Yukon EC Id 0xb6 Rev 0x02> on mskc0 kernel: msk0: failed to allocate DMA'able memory for jumbo buf kernel: device_attach: msk0 attach returned 1 I would have to reboot to solve this situation. Google found me not much information, but someone did mention something about MSI. I set hw.pci.enable_msix=0 and hw.pci.enable_msi=0 in my loader.conf, and I was able to reach megas of bytes throughput without a problem. - -- llwang -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.3 (FreeBSD) iD8DBQFGUIhDCQM7t5B2mhARAjRiAJ9sUZY2r1Js/ZUc+hV0cq9zrtAyJACfbihs vgaKBUNWLC4Y8LSZ39vxBI8= =4bxd -----END PGP SIGNATURE-----
