PPC 405 OCP EMAC MAL problem

[l.lucrezia.tiesse at iol.it]

We have developped a board with NPE405 processor with PPC Linux 2.4.20 kernel, we also have reported various patchs to ibm_ocp device driver, but when we run a test that outputs via FTP big files of both ethernet interfaces contemporarly, we observe that there is a period (few seconds) in which we did not receive any data, then we get a RXDE interrupt and then we see a RXEOB interrupt pending on the MAL, CPU is not interrupted at all.....

Does somebody have any idea ?

thanks a lot
