>Description:
On a SPARCstation 10 equipped with two SM71 cpus I am running a
Netgear MA401 wlan card in a nell sbus-pcmcia bridge. With an SMP
enabled kernel and the MA401 inserted, the ss10 will hang in tsleep()
during shutdown.

(Kernel configured with DEBUG and DIAGNOSTIC options.)
This does not happen with a kernel that lacks SMP support. In
addition, the frequent
stray interrupt ipl 0x7 pc=0xf0007e84 npc=0xf0007e88 psr=404000c7<S,PS>
log entries only show up with SMP support.
A reboot has to be enforced by breaking into the kernel debugger and
issuing 'reboot' which usually works.
Replacing the netbsd-3 stp4020.c with the -current code did not help.
>How-To-Repeat:
Set up an SMP sparcstation with a nell(4) bridge and a prism card
(wi(4)) as wlan access point. Note that every time you shut it down,
it hangs.

Here goes... You can find the discussion predating the PR under
http://mail-index.NetBSD.org/port-sparc/2005/11/05/0000.html - the
situation is more or less unchanged. The wi(4) card is not probed during
boot and needs to be re-plugged a few times (PR 30549).

Hi,
thanks for looking at the issue. It's been a while... I ended up getting an
external wlan access point in place of the pcmcia card, and the machine has
morphed into an SS20 in the meantime.
I can drop in the nell, and try a -current kernel; in fact, I have a
sort-of-current installation around from testing the waters, since it looks
like netbsd-5 on sparc-mp is never going to happen, and things from a newer
version of pf(4) to wapbl look tempting. Fine-grained locking changes have
broken appletalk support on many ethernet interfaces, though - not le(4)
but hme(4).
OTOH, I'd definitely be interested in netbsd-4 patches, since that would be
more of a drop-in replacement, pf compatible and all. Plus, it's the last
usable release on sparc-mp. Just tell me if the patches are much of an
effort.

yeah - it has been a while... thank you for your patience :)

oh - the patches i'm talking about are the final smp stability changes
i've made in -current, backported to netbsd-5. once that pullup is
executed, netbsd-5 branch will be mostly stable for sparc. it has a
(soft) hang that i don't see on -current, but only after a really long
time of significant load...

let me see about porting just the hardclock change itself to netbsd-4.
thanks.

I added the nell(4) with a wi(4) card, booted a 5.99.47 MP kernel with the
netbsd-4 userland, configured the wi(4), and could shut down the ss20 (2x
SM71) to the OF prompt just fine.
Problem fixed. Good job! :)

Responsible-Changed-Why:
i'm pretty sure i know what the problem is that and it is fixed in -current
and fixed in a pending netbsd-5 pullup, and i have a backport of the fix
to netbsd-4 in testing.

I provided feedback.
I set the state back to "open" since the issue is still
relevant for netbsd-4.
