I have isolated the point at which current no longer runs as Jan 31 -
Feb 1 of this year. Prior version work fine, in Feb & Mar I get
either "Kernel trap 9 with interrupts disabled" or I think the same
thing with trap 26 (really not sure on that one).
Next I took a brand new current from this evening and tried it - it
still hangs, but a keypress on the keyboard pretty much always breaks
it out of the hang and into a normal boot.
Now, I finally got the equipment and time together to remote gdb the
bad kernel and here's what I get:
I set a breakpoint at cam_xpt.c::xpt_config() - this is where the
"Waiting 15 seconds.." message is from and stepped down through it. I
get through the first xpt_for_all_busses (xptconfigbuscountfunc,...)
and then I hit the second one (~line 6749 of cam_xpt.c) I pass through
several things, including the xptconfigfunc() and end up in
subr_autoconf.c::run_interrupt_driven_config_hooks(). At the bottom
of this function there is a tsleep that gets called - this is
apparently where it hangs. If I hit a key on the keyboard it will
continue on past this point and all seems to work fine from then on.
This is my first time this deep into the kernel - can you suggest a
further plan of attack?
thanks!
