Hi,
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 several Mbytes throughput without
a problem.
