    Has there been any change in this?
    I was playing with my Ultra 45 systems again, and tried updating to 
 NetBSD 9.0_BETA, and am seeing the same kind of behaviour, except with 
 mpt.  My 8.1_STABLE system works fine (although I have to increase the 
 kernel stack size to get through the boot).
    I noticed that sparc64 switched from gcc6 to gcc7 back in Februrary, so 
 my first wild guess is something in gcc7 may be causing the problem. 
 There were no noticable changes in the mpt code between NetBSD-8 and 
 NetBSD-9, so I don't know if the problem is in the mpt code, or something 
 else it uses.
    I will probably try this again with an older tree that still has gcc6 
 and I can try with both versions).  I was doing that a year ago when I was 
 having trouble with the Ultra 45 crashing while configuring the audio 
    I had also tried a current autobuild kernel, which fails in the same 
 way, but also does not crash in the audio driver.
