Dear you.
Hello.

I have some problem.
First of all, My machine is...
ATMEL CPU(ATM7TDMI Core)
FPGA (AMBA Controller and Misc. logic and so on)
RAM: 2MB
CS8900A Ethernet controller.

The uClinux 2.4.x was ported in my machine.
It's OK. UART was well doing and login program was good without cs8900
driver.
But cs8900 was loaded and On receiving a packet (ARP packet), the message
"kernel BUG at page_alloc.c:90!" happened.
Did my machine have small RAM ?
When login was good without cs8900, I commanded "du" and I saw that /var
directory was 55KB totally, 5KB was used and only 50KB was avaiable. Isn't
50KB free RAM  enough ?

Please help me.
Please give me advice.

Thank you.
Have a nice day.


The below message is what I saw.
