This would seem to suggest a problem with skge itself, although
there might be some other interaction with bonding that causes the
problems for that case.
In both of the above mentioned cases, I was not using bonding. That
was with the skge driver only.
The above tests both work fine with the 2.6.20.1 sk98lin driver loaded
as "modprobe sk98lin RlmtMode=DualNet".
I can change the MTU, add and remove eth2/eth3 from the bond, and up and
down the interface. It also works fine with different hardware (e100,
e1000, tg3, bnx2). Running both interfaces alone without the bonding
driver also works (I can up and down the interfaces with no
side-affects).
Just an update - it looks like 2.6.20.1 fixed the MTU problem ("1"
above), but not the other problem (where the machine locks up if the
second port on the dual-port card is downed).
To recap:
I am use SysKonnect SK-9843 cards. The sk98lin driver works fine; the
skge driver does not. The following sequence of commands locks up the
server. The lock is a hard lock; console is not responsive to keyboard
input or to sysrq. Nothing is printed on the serial console.
ip li set eth2 up
ip li set eth2 down
ip li set eth3 up
There are no addresses assigned to either interface. This was done after
a fresh boot. It is repeatable. If I do not down eth2, I can up eth3
assign addresses, and use both interfaces.
The kernel is fresh from kernel.org and does not have any third party
patches.
