The box has no HiSax card installed. the reason for the crash is add_timer() done on an already running timer. This happens because for some reason CARD_INIT is called twice. this patch works this problem around by using mod_timer() - this gets a booting system - but it would be nice to figure out why CARD_INIT is done twice. the ISDN config section (generated via make randconfig) is this: # # ISDN feature submodules # # CONFIG_ISDN_DRV_LOOP is not set CONFIG_ISDN_DIVERSION=y # # ISDN4Linux hardware drivers # # # Passive cards # CONFIG_ISDN_DRV_HISAX=y # # D-channel protocol features # CONFIG_HISAX_EURO=y CONFIG_DE_AOC=y # CONFIG_HISAX_NO_SENDCOMPLETE is not set # CONFIG_HISAX_NO_LLC is not set # CONFIG_HISAX_NO_KEYPAD is not set CONFIG_HISAX_1TR6=y CONFIG_HISAX_NI1=y CONFIG_HISAX_MAX_CARDS=8 # # HiSax supported cards # CONFIG_HISAX_16_0=y # CONFIG_HISAX_16_3 is not set # CONFIG_HISAX_TELESPCI is not set CONFIG_HISAX_S0BOX=y # CONFIG_HISAX_AVM_A1 is not set CONFIG_HISAX_FRITZPCI=y CONFIG_HISAX_AVM_A1_PCMCIA=y CONFIG_HISAX_ELSA=y CONFIG_HISAX_IX1MICROR2=y CONFIG_HISAX_DIEHLDIVA=y # CONFIG_HISAX_ASUSCOM is not set # CONFIG_HISAX_TELEINT is not set CONFIG_HISAX_HFCS=y # CONFIG_HISAX_SEDLBAUER is not set CONFIG_HISAX_SPORTSTER=y # CONFIG_HISAX_MIC is not set # CONFIG_HISAX_NETJET is not set # CONFIG_HISAX_NETJET_U is not set # CONFIG_HISAX_NICCY is not set # CONFIG_HISAX_ISURF is not set # CONFIG_HISAX_HSTSAPHIR is not set # CONFIG_HISAX_BKM_A4T is not set # CONFIG_HISAX_SCT_QUADRO is not set # CONFIG_HISAX_GAZEL is not set # CONFIG_HISAX_HFC_PCI is not set # CONFIG_HISAX_W6692 is not set # CONFIG_HISAX_HFC_SX is not set # CONFIG_HISAX_DEBUG is not set # # HiSax PCMCIA card service modules # # # HiSax sub driver modules # CONFIG_HISAX_ST5481=y CONFIG_HISAX_HFCUSB=y # CONFIG_HISAX_HFC4S8S is not set CONFIG_HISAX_FRITZ_PCIPNP=y CONFIG_HISAX_HDLC=y # # Active cards # CONFIG_ISDN_DRV_ICN=m CONFIG_ISDN_DRV_PCBIT=m CONFIG_ISDN_DRV_SC=y # CONFIG_ISDN_DRV_ACT2000 is not set CONFIG_HYSDN=m # CONFIG_ISDN_DRV_GIGASET is not set # CONFIG_ISDN_CAPI is not set CONFIG_PHONE=y CONFIG_PHONE_IXJ=m Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Karsten Keil <kkeil@suse.de> Cc: Kai Germaschewski <kai@germaschewski.name> Cc: "Rafael J.
