Collection of small Alpha issues

Hi,

NetBSD/alpha has been running wonderfully on my AlphaServer DS25 for a 
while now since thorpej fixed lots of things. However, there are still a 
few things that are a bit buggy.

First, I'm seeing an issue where multiple runnable processes stay on just 
one processor, like so:

load averages:  2.04,  2.09,  1.93;               up 34+10:47:53   14:10:
84 processes: 2 runnable, 79 sleeping, 1 stopped, 1 zombie, 1 on CPU
CPU0: 59.5% user, 33.7% nice,  6.4% system,  0.4% interrupt,  0.0% idle
CPU1:  0.4% user,  0.0% nice,  0.7% system,  0.5% interrupt, 98.4% idle
Memory: 6073M Act, 2966M Inact, 12M Wired, 123M Exec, 7814M File, 3696K F
Swap: 24G Total, 24G Free

   PID USERNAME PRI NICE   SIZE   RES STATE       TIME   WCPU    CPU COMMA
14054 john      26    0    15M 9712K RUN/0      11:05 58.98% 58.98% mini-
  9576 pbulk     24    4   258M  240M RUN/0       0:12 33.91% 28.03% cc1pl

cpuctl shows nothing out of order:

Num  HwId Unbound LWPs Interrupts Last change              #Intr

Second, several pkgsrc builds fail similarly:

In file included from vm.c:360:0:
vm_eval.c: In function 'rb_eval_cmd_kw':
vm_eval.c:1929:1: internal compiler error: in move_insn, at 
haifa-sched.c:5444
  }
  ^
no stack trace because unwind library not available

Any idea how to fix these?


Third, is there any reason to care about unaligned accesses from sendmail?

Starting sendmail.

va=0x3fffd6261b2 pc=0x12001d114 ra=0x12001ce44 sp=0x1ffffd1d0 op=ldl
[ 2975706.6559539] pid 24869 (sendmail): unaligned access: 
va=0x3fffd626242 pc=0x12001d114 ra=0x12001ce44 sp=0x1ffffd1d0 op=ldl
...


Fourth, firefox52 compiles, but it doesn't run:

(No debugging symbols found in firefox52)
(gdb) run

Thread 1 "" received signal SIGSEGV, Segmentation fault.

I can rebuild with symbols, or I can give a shell to anyone who wants to 
have a gander.


It'd be lovely if these things are fixed for NetBSD 10 :)

Thanks,
