Machine Check error in Embedded Planet Board

Machine Check error in Embedded Planet Board

[Narendra]

Hi All,

I am working on WLAN driver for Embedded Planet RPXLITE board on
Hard Hat Linux 2.0.

When i start a ping session of packet size 1400 or above.
Initially it works fine and after responding to around 200
packets, there is a machine check error occuring in function
in_be16().

NIP --- points to the routine where i will be in loop to read the
received data.

Any idea why this is happening??
Is this any problem with Kernel or with Embedded Planet board?

Thanks in Advance,
Naren

Here is the oops message that i get everytime,
Machine check in kernel mode.

Try disabling bus timeouts.
