Then, there's a lot of these: eth0: Tx timed out, lost interrupt? TSR=0x4, ISR=0x15, t=52. eth0: Tx timed out, lost interrupt? TSR=0x5, ISR=0x3, t=33. eth0: Tx timed out, lost interrupt? TSR=0x5, ISR=0x3, t=36. but the PCMCIA network card of mine can also be flakey. Both kernels have been cross-compiled with gcc 4.6.1. I'll be happy to provide you with the kernel config and the full dmesg output if you need them. Regards, Tuomas
