Ah, dc(4), everyone's favorite buggy NIC. I've got a system with
a dc(4) that I am trying to move to 5-CURRENT from 5.2.1-R. Here's
the info on the NIC,
dc0@pci0:9:0: class=0x020000 card=0xf0022646 chip=0x000211ad rev=0x20 hdr=0x00
vendor = 'Lite-On Communications Inc'
device = 'NGMC169B 10/100 Ethernet (NetGear FA310TX)'
class = network
subclass = ethernet
It has been working alright in 5.2.1-R, but with CURRENT, I end up with,
dc0: failed to force tx and rx to idle state
dc0: failed to force tx and rx to idle state
dc0: watchdog timeout
dc0: failed to force tx and rx to idle state
dc0: watchdog timeout
dc0: failed to force tx and rx to idle state
dc0: watchdog timeout
The 'failed to force tx and rx to idle state' are not new. I would get
those at boot time with 5.2.1-R, but the 'watchdog timeout' is new. The
NIC is no longer working at all. No traffic going in or out.
I noticed that the src/sys/pci/if_dc* files had had some changes since
5.2.1-R and tried regressing just those, but it had no effect. Bummer,
since it looked like 1.138 of if_dc.c was a good candidate for causing
the trouble. Anyone else have this card and see this? Ideas about what
may have changed?
Some dmesg(8) output,
dc0: <82c169 PNIC 10/100BaseTX> port 0xd800-0xd8ff mem 0xde000000-0xde0000ff irq 9 at device 9.0 on pci0
