DragonFly kernel List (threaded) for 2004-03
Re: Kernel Panic on boot
:I downloaded the 2004-03-17b ISO and tried that. The result is the
:same. I've attached a verbose boot, but it's essentially the same as
:the last, The "Preloaded elf kernel" address is different and some of
:the log output is in a different order, but the trace is the same.
:Any more ideas?

Ah. One advantage of using the ISO is that I can convert some of
the addresses to symbols without having to ask you more questions.
instruction pointer = 0x8:0xc00eb747
stack pointer = 0x10:0xc05ccaec
frame pointer = 0x10:0xc05ccaec
current process = 0 (swapper)

I think it would be helpful if you generated the contents of the
stack. e.g. if the stack pointer is 0xc05ccaec then use the
'examine' command at the db> prompt to examine a bunch of the stack
(do a lot):
db> exam 0xc05ccaec (start at the 'stack pointer', which may
be different each time it crashes so check it).
db> <return> Just hit return for each line of output after
the first exam command.
Unfortunately, I have no idea about c00eb747... that's like in the BIOS
somewhere, I think, but I would have rexpected the system to be in
VM86 mode in that case and it isn't. Weird.
I think Joerg may be on to something here.
