• erc32sonic/erc32sonic.c: Minor modifications which enable network interface to come up and work for some time before getting an error in the SONIC driver. The error is a bit random, sometimes MCLGET (m, M_WAIT) tries to access memory way outside the available ram (and traps) while sometimes there is a panic due to RBAE/RXEN.
