i have the following custom board:
Freescale ColdFire MCF5307
4MB Flash, with 2.6.36 main line kernel
16MB sdram
dm9000e ethernet chip.
I succesfully slightly modified the dm9000.c driver to work with this big endian cpu, ping (in and out) and telnet server are working fine now.
My issue now is that, once launched httpd with a simple index page, refreshing continuosly the page from a browser cause a kind of kernel trap error:
Seems some splinlock issue, issued from inside the dm9000_interrupt routine, the kernel then continue to work, the packet sending also seems to works still, but the network packet receiving is not working anymore. Looking with an oscilloscope, the interrupt signal receving packet is still issued from the dm9000 chip, the /proc/interrupts is showing that the interrupt count still increasing, but the kernel seems not handling it anymore.
I tried to get some help in the kernel mailing list, but there is too much patch/development jub there and i couldn't get any help.
