How-To-Repeat: Switch active console from one blade to another. 6.x-RELEASE was fine.
Comment 1 Helmut Schneider 2008-04-18 15:59:54 UTC



This had been fixed with 6.2 and reappeared with 7.0.
Comment 2 Helmut Schneider 2008-04-21 20:21:21 UTC
After further investigation it turns out the the problem is the keyboard 
controller. While this is not that serious as a problem with ACPI would be 
FreeBSD should not panic because of "plugging in a keyboard".

 hint.atkbd.0.disabled="1" is a sufficient workaround.

Helmut, can we please have a backtrace and the actual panic

Helmut: Additionally to the requested panic msg + bt, can you please

Comment 5 Helmut Schneider 2008-05-18 09:05:13 UTC
panic message and backtrace:

What might be interesting, too, if hint.atkbd.0.disabled="1" or 
hint.atkbdc.0.at="acpi" are set a "dmesg -a" looks normal:

Without the last thing that is logged is "Trying to mount root from 

With hint.atkbdc.0.at="acpi" the kernel does not panic.
Comment 6 Volker Werth freebsd_committer 2008-05-18 16:16:56 UTC
State Changed
From-To: feedback->analyzed

feedback provided 
it appears to be an atkbdc problem (backtrace + panic received) 
a workaround is to attach atkbdc to acpi instead of isa 
from /boot/device.hints 
this needs to be fixed in isa drivers but I think we need to discuss 
the device.hints defaults in an ACPI world 

Comment 7 Volker Werth freebsd_committer 2008-05-18 16:16:56 UTC
Responsible Changed
From-To: vwe->freebsd-i386

I think this is more appropriate to i386, 
but may also partially belong to arch or acpi 
Over to maintainer(s).
Comment 8 Remko Lodder freebsd_committer 2011-10-24 15:30:45 UTC
Responsible Changed
From-To: freebsd-i386->freebsd-acpi

This didn't get solved in the i386 category, since Volker also suggests that -acpi 
might be one that could fix this, assign it there and try to get someone to look 
at this :)

The linked backtrace no longer exists.
