>Organization:
The NetBSD Foundation, Inc.
>Environment:
System: NetBSD big-apple.aprisoft.de 11.99.4 NetBSD 11.99.4 (POWERMAC_G5.MP) #138: Mon Jan 5 16:17:29 CET 2026 martin@seven-days-to-the-wolves.aprisoft.de:/work/src/sys/arch/macppc/compile/POWERMAC_G5.MP macppc
Architecture: powerpc
Machine: macppc
>Description:

Running this machine with a -current kernel as of earlier today causes
the machine to lock up after a few minutes of regular use.

Lock up means:

 - mouse freezes / keyboard does no longer toggle num-lock or similar LEDs
 - X freezes
 - audio keeps playing untill buffer is drained and then goes into a loop
 - machine does not answer pings 

>How-To-Repeat:

Boot a G5 and wait?
Last working kernel I have is from Jan 5, so quite old.

>Fix:
n/a
