We have a software interrupt mechanism via the SWI_* defines in sys/interrupt.h. Various bits of code use them, for example the kernel task queue (kern/subr_taskqueue.c), CAM (bus/cam/cam_xpt.c), and a few others. -Matt Matthew Dillon <dillon@backplane.com>

Re: Kernel panic during boot in usb_add_task
I could track it down where the panic occurs: http://opengrok.creo.hu/dragonfly/xref/src/sys/bus/usb/usb.c#374 More specifically: http://opengrok.creo.hu/dragonfly/xref/src/sys/sys/queue.h#428 *(head)->tqh_last = (elm); This expands to: *(&taskq->tasks)->tgh_last = task; There a NULL pointer is dereferenced somehow. usb_add_task is called from uhci_timeout: http://opengrok.creo.hu/dragonfly/xref/src/sys/bus/usb/uhci.c#1428 It seems to get only called when a ...

Re: Kernel panic during boot in usb_add_task
Looks to be decent detective work to me! But I quit coding in 'C' the same year the 386-16 was launched, ;-) ..so we'll now need to wait for a developer to weigh-in. Meanwhile - it is not *supposed to* matter - but on any OS that you are able to boot with the devices all optioned ON, can you confirm use of shared interrupts or NOT? Ex: Tyan Tomcat - some sharing: triligon# ps -xa | grep '\[irq' 22 ?? WL 0:00.00 [irq9: acpi0] 23 ?? WL 0:07.04 [irq16: bge0 ...
