This problem (unaligned access fault) is specific to the alpha. Can you compile a kernel with debugging enabled (config -g CONFIGFILE) and map the PC and RA to lines in the source code? Eg: % gdb kernel.debug <..> (gdb) l *0xfffffc0000387a34 Please crash the machine with the new kernel and use the pc/ra numbers from the new crash with the new kernel. The fastest path to getting your machine working might be to get another network card (3c90x, Intel EtherExpress Pro, a tulip based cards are known to be good).
