Re: more on supermicro 6010H hang

[Dave Cornejo]

Well, damn.

I've run it through a couple of reboots with a fresh current SMP
kernel and it boots like a champ... 

Where were you a couple of weeks ago when I started trying to solve
this problem? ;-)  At least I learned a lot about debugging kernels...

thanks for your guess!

This is probably not it, but it's worth a peek.  Check your BIOS
settings and see if there's one that controls whether the USB
interrupt is enabled.  Make sure that this interrupt is enabled.  If
it's not, I know you can get hangs at exactly the point where the
"Waiting 15 seconds.." message comes out.

more on supermicro 6010H hang

[Dave Cornejo]

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!
