Subject: [BUG] Sky2 driver in 2.6.22-rc5-git1-cfs-v17
Hi,
recently have started to see this in my dmesg:
NETDEV WATCHDOG: eth0: transmit timed out
sky2 eth0: tx timeout
sky2 eth0: transmit ring 449 .. 408 report=449 done=449
sky2 eth0: disabling interface
sky2 eth0: enabling interface
sky2 eth0: ram buffer 48K
sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control rx
I'm not using MSI since it seems to have caused problems in the past.
I run with a 9k mtu
sky2 eth0: transmit ring 18 .. 489 report=18 done=18
---- I assume ring max is 512 (ie 1-512) since:
Ring parameters for eth0:
Current hardware settings:
RX: 168
RX Mini: 0
RX Jumbo: 0
TX: 511
And 489 + 41 - 18 = 512
sky2 eth0: transmit ring 197 .. 156 report=197 done=197
sky2 eth0: transmit ring 480 .. 439 report=480 done=480
sky2 eth0: transmit ring 413 .. 372 report=413 done=413
sky2 eth0: transmit ring 320 .. 279 report=320 done=320
Else, they are all off by 41.
Is this a known bug?
Comments? ideas?
Offload parameters for eth0:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: on
udp fragmentation offload: off
