----------------------------------------
I have now too many of these Gigabyte mobos, GA-965GM-S2 with the Marvell
88e8056
www.gigabyte.com.tw / Products / Motherboard /
Products_Overview.aspx?ProductID=2388
Observations.
-------------
The problem may not be sky2 specific. I have diskless nodes where too many can
NOT
1) reliably DHCP an IP number from the server
2) and if the pxelinux.cfg/default loads, it is not certain if the kernel or
the initrd would tftp transfer.
There are two of 12 diskless nodes that work, ... always work.
All mobos are the same, all CMOS is set identically
Please do not hesitate to ask for further observations on the functionality of
the sky2 module.
--------------------------------
lspci is at the bottom of this post.

Thank you, "Rob Ogden" <kernel (at) zeppo . hm . uc . edu>
Details
-------
0) All systems w/ Intel Core2duo/6600, 2GB-RAM
1) DHCP/PXE-boot/NFS server
Suse10.0 2.6.21 was 2.6.18
2) Diskless clients
Suse10.0 2.6.18 or 2.6.19 or 2.6.21
I believe that the 2.6.21 kernel is using a patched sky2 but I am not
remembering how recent.
3) I have played with sky2 and with sk98lin from Marvell
There is no change in what works and does not work.
4) Netgear 24-port Gigabit unmanaged switch
The first 4 examples of this mobo worked w/o trouble on gigabit network.
These were the ones I used for setting the configuration.
As I took this configuration to waiting diskless clients, I began to experience
the troubles, stopping after 9 failures out of 10.
On the bench there are 3 systems.
1) DHCP/BOOT/NFS server (no problems here)
2) Diskless node #1 (always works)
3) Diskless node #2 (will always fail at some point)
I can get much better but not reliable service from system #2 if I boot it with
a Knoppix 5.1.1 CD 2.6.19 kernel.
Several times a 1GB file can "/usr/bin/scp" back and forth at 40MB/sec - going
from RAM-DISK to RAM-DISK
But if I make it too busy, it will fail.
Failure comes sooner if I exercise an NFS-mount
Failure variously features -
"kernel panic"
"link down"
"Corrupted MAC on input"
"transmit descriptor error (hardware problem)"
AND an error from marvell's driver

> Msg: Mac Transmit FIFO underrun
I have flashed the BIOS from F4 to F5 to F6(latest)
Perhaps not unexpectedly, BIOS F1 exacerbates the failure.
--------------------------------
How to get system #2 NOT to fail
--------------------------------
The system #2 will NOT fail if it boots and the ethernet is then using an
installed PCI-card/RTL8169 chip.
The system #2 will NOT fail when connected to a 100mbit Linksys switch
The system #2 will NOT fail when connected to 1000mbit netgear AND running
Win-XP (although throughput seems to drop below 7MB/sec)
Thank you for your help on this.
