Subject: What is this: skge Ram read/write data parity error

Hello,

Since some time I'm getting the following log entries under 2.6.15:

Mar 7 05:42:48 tiger kernel: skge Ram write data parity error
Mar 7 05:42:48 tiger kernel: skge Ram read data parity error

Does this mean my hardware is faulty? The error message seems to imply
that, but since I am not experiencing any problems and a comment in
skge.c says

/* Parity errors seem to happen when Genesis is connected to a switch
* with no other ports present. Heartbeat error??
*/

talking about some other sort of parity error though ("mac parity") I'm
not sure any more. Can anybody enlighten me?

Thanks,
Aaron

Which exact hardware is that, look for the skge line in the kernel log (dmesg)?

I am not a hardware wizard, but I wrote that comment. My guess is that it shows
up when the hardware decides to clock in some data that isn't really a packet
(line noise, etc). Both skge and sk98lin just clear the error and keep going.

Does it happen a lot or just once?
