Is anyone actively working with ethernet on the 440GX? I'm seeing TX lockups when stressing the 10/100 EMAC with heavy NFS traffic:
find /nfs_mnt -type f |xargs grep blahblahblah This is the only way I can make it happen, but it does happen quickly. The 'get_next_packet' bit is set but never clears. The EMAC_ISR doesn't have any unusual errors (except for some deferrals). The 'dead_bit' is _not_ asserted. The MAL channels are enabled, and so is the EMAC. No TXDE interrupts have occurred. The BD ring is filled with packets ready to send. The same code on a 440GP works fine. This version of the CPU (PVR 0x51b21851) is supposed to have all the EMAC-related errata fixed, but this smells like a silicon bug to me. I'm still waiting on a response from IBM... Any ideas?
