freebsd stable - Mar 2010 - msk gigabit NIC missed interrupts and watchdog timeouts

Hello,

I am testing FreeBSD-8_STABLE updated as of a few minutes ago along
with a msk type NIC.

Having trouble with missed TX interrupts and watchdog timeouts.

Tested http://svn.freebsd.org/changeset/base/205161 which made the NIC
a little more stable but it finally exhibited the same issues after 10
minutes of load vs 1 minute.

Does anyone have any suggestions on things that I can do to make this
NIC more robust?

pciconf -l shows:
  mskc0@pci0:2:0:0:	class=0x020000 card=0x34588086 chip=0x436111ab
rev=0x18 hdr=0x00

dmesg -a | grep msk shows:
  mskc0: <Marvell Yukon 88E8050 Gigabit Ethernet> port 0xc800-0xc8ff
mem 0xdedfc000-0xdedfffff irq 16 at device 0.0 on pci2
  msk0: <Marvell Technology Group Ltd. Yukon EC Id 0xb6 Rev 0x02> on mskc0
  msk0: Ethernet address: 00:0e:0c:a4:54:ad
  miibus0: <MII bus> on msk0
  mskc0: [FILTER]

Thanks in advance for any pointers, etc

Scott

Would you try latest msk(4) in HEAD? I think you can download
if_msk.c and if_mskreg.h from HEAD and can build it on stable/8.
Due to added interface capabilities you have to add the following
code in the beginning of if_msk.c to build it on stable/8.

#ifndef IFCAP_VLAN_HWTSO
#define IFCAP_VLAN_HWTSO	0
#endif

Also show me the output of "devinfo -rv | grep phy".

No problem.  Just compiled a kernel containing the newest files.

nas2# devinfo -rv | grep ph
                  e1000phy0 pnpinfo oui=0x5043 model=0xc rev=0x2 at phyno=0

I am now testing the new kernel and it has been under load for quite a
while.  I shifted 2+ gigabytes through it and it seems OK now.

Thanks for the help !!
