The detection would take place in dev/cm/smc90cx6.c (cm_attach): > linkaddress = GETMEM(CMMACOFF); // CMMACOFF is 1 In fact, not only the offset 1, but any offset I read is "0xF5". This leads me to think there could be some breakage around memory handling. smc90cx6var.h: > #define GETMEM(off) \ > bus_space_read_1(rman_get_bustag((sc)->mem_res), \ > rman_get_bushandle((sc)->mem_res), \ > (off)) The card otherwise works fine in DOS and Linux (both can read the link address correctly). I also tried with another card, same model. It made no difference. Also tried setting the card to actually have 0xf5 link address, but it still didn't work. >How-To-Repeat: Try to use it. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
