I tuned on some debug sysctls, here is the result. cbb0: card inserted: event=0x00000000, state=30000810 pccard0: chip_socket_enable cbb_pcic_socket_enable: cbb0: cbb_power: 3V pccard0: read_cis cis mem map ce6e1000 pccard0: CIS tuple chain: CISTPL_NONE 00 CISTPL_NONE 00 [....] CISTPL_CHECKSUM too short 0 10 00 CISTPL_NONE 00 CISTPL_NONE 00 [and it continues like this until the panic]

Whatever pccard i insert, here an unsupported 3Com OfficeConnect WiFi card or even a Intel Pro/100+ Mobile16 card it panics like seen below. This happens if booted with the card inserted and if hotplugged. The laptop is booted "diskless" so I can't produce a crashdump (the info below is typed by hand).
