 still crashes with this weeks -current build.  looks
 the same as my prior report except that it now reads:

 Invalid memory access at   %SRR0:  00000075    %SRR1:  00007500

 ie, the values in %SRR0 and %SRR1 are different now.

 Is there a workaround for installing NetBSD on a PowerBook or does nobody run NetBSD on that Hardware?

 I don't know, but there are a lot of powerbook models and I don't
 think this issue affects most of them.

 Just picked a 867Mhz 15" PowerBook which may possible be the lower spec
 sibling of Eric's 1Ghz system (PowerBook3,5).

 Issue still persists with latest ofwboot.xcf and netbsd from HEAD.

 On a cold boot, I get:
 Decrement exception at %SRR0: 0000006c %SRR1: 00006c6a

 Rebooting and trying again, I get:
 Invalid memory access at %SRR0: 0000006c %SRR1: 00006c6a

 Different error messages, but same addresses.

 ah, i guess i never sent this info to the PR.

 a short while ago i tested building a kernel with FIRMWORKSBUG
 option enabled.  this gives a different failure mode -- but
 unfortunately it hangs hard instead of giving you the prom.

 so the problem may be related to openfirmware() on these
 systems.

 I started looking around too see if I could find anything else out.
 I stumbled across this alternative bootloader[1], it produced the same
 results as I previously reported. Just for fun I tried using our kernel
 with the OpenBSD ofwboot, everything failed the same way (invalid memory
 access). OpenBSD ofwboot has no such issue booting their bsd.rd however.

 Reason I was pocking at bootloader was because I came to this PR from
 another related to booting the G4 Mac Mini, and there uwe poked at
 ofwboot.xcf.

 yeah, i don't think ofwboot is the issue.  unless it fails to setup
 the kernel properly, it's the early kernel running that hangs, so
 the fix is very likely in the startup code.

 In my recent G5 hackery I had similar issues with OF loading the kernel
 directly - IIRC OF throws this error if we somehow cause an interrupt
 ( not necessarily a decrementer exception ) early on before installing
 our own handlers.

 have fun

 In https://markmail.org/message/nmzthacf33qdfd7b, Philip Schulz states

 "I haven't experienced the issue myself, but I think what happens is
 that Open Firmware enables interrupts before the kernel has a chance
 to install its own exception handlers. I have seen reports that the
 exception occurs both on NetBSD and OpenBSD. The latter seems to have
 added a workaround: They set the decrementer register to a very high
 value, very early in the boot process (possibly even in their loader)."
