 I'm not sure if this is the same issue but booting the 7.1 netbsd.macppc from
 the provided disk image does not work on my PowerBook G4 (2005).
 
 When I run
 
 boot cd:,\ofwboot.xcf netbsd.macppc
 
 loading the xcf seems to work fine, but then I get
 
 5926884+130584=0x5c71fc
  start=0x100000
 
 Decrementer exception at   %SRR0: 004d51e0   %SRR1:00003030
  ok
 
 Now, I found someone on the internet who seemed to have had a similar problem in
 2008, booting FreeBSD (markmail.org/message/nmzthacf33qdfd7b) where somebody
 else suggested setting the decrementer register using `1 1f lshift not dec!` as
 a workaround (I'm not really that familiar with OpenFirmware). After rebooting
 and trying that out the new failure message reads:
 
 5926884+130584=0x5c71fc
  start=0x100000
 
 Invalid memory access at   %SRR0: 004d51e0   %SRR1:00003030
  ok
