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.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
