Sorry if this is a re-run, but it looks like the original got lost somewhere. This problem may be CAM specific. I am not sure what to do about this one. Since I got my machine I have not been able to build a kernel that runs, without using "swap on generic" and -a at the boot prompt Well, after doing some debugging, it looks like the line dev_t rootdev = makedev(4, 0x000020000); in swapkernel.c (/usr/src/sys/compile/<foo>/swapkernel.c) isn't being run. The fatal trap 12 I was getting is caused by major(rootdev) being 0, thus deferencing bdevsw[major(rootdev)] deferences null. If I copy the rootdev assignment into setconf() (in swapkernel.c), the resultant kernel does not need the "swap on generic", and will happily boot unattended. Anyway, yes, I realize that the global variable *should* be set. On my machine thoough, using a freshly built system from current sources (e.g. this week), it isn't. So, what need to be done to get this fix in place? It seems I am not the only one with this problem. +C -- Thinking of purchasing RAM from the Chip Merchant?
