Hiya,
At the bottom of this message is the dmesg output from my 4.0-CURRENT box
with a kernel compiled February 27th. The kernel as of a cvsup this
afternoon now dies and prints the following message immediately after
initializing the keyboard:
<snip>
atkbdc0: <keyboard controller (i8042)> at port 0x60-0x6f on isa0
atkbd0: <AT Keyboard> irq 1 on atkbdc0
panic: free: multiple frees
If someone can't figure out where this might be coming from I'll hook up a
serial console and try to capture a verbose boot.
My kernel config is also included at the very bottom.
Thanks, Ben
