1.6_BETA3 /cats crashing

Since I installed the 1.6_BETA3 using the 28 June daily build from releng.netbsd.org, I've been
experiencing crashes everytime the machine is under load.  I haven't made a careful note of the error, but I
will do next time it crashes.  It's something like:

Non-trapped page fault with intr_depth>0

Is this a known-about-and-being-worked-on issue, or do I need to note the details, and post my kernel
config, etc?  The machine was pretty solid under 1.5.2.  Only two things have changed in my config:  I'm now
using tlp0 rather than de0 for my network card and I'm not disabling INET6 anymore.  (On at least one
occasion I did notice that the tlp driver was named, but I can't be sure that's a regular occurence.)

Cheers,

David.

PS - Apologies for the cross-post, but port-cats doesn't seem very busy, so I don't know if I'm talking to
myself there.

1.6_BETA3 /cats crashing

Further to my previous email, it has happen again, and the exact message is:

Non-emulated page fault with intr_depth>0
Data abort: 'Translation fault (page)' status=007 address=f72b49c4 PC=f021d378
Stopped in pid 5938 (cc1) at 0xf021d378: stmia r0!, {r3-r4, r12, r14}

At the time, I was compiling pine from pkgsrc, and there was some network traffic, but otherwise the machine
wasn't doing anything (i.e. no X or anything like that).

Cheers,

David.

Any chance of a trace?

Could you also try a kernel that doesn't have tlp but instead has de in
it?

I'm not overly enamoured with tlp on cats, it doesn't work for me. 
Certainly I need to spend a weekend playing and figuring out what's
broken, note that it's the cats somewhere (as tlp works fine with the
same card on i386)

I'm rather tempted to switch the GENERIC kernel back to de from tlp,
until cats works with tlp.

PS I'm on port-cats so be assured there are ppl on it.

I was just composing a jubilant email about how with de it was now sustaining load levels > 7.  However, after a
short time, it fell over again, same error.  That said, the machine is rarely at the sort of load level
anyway, so I can't be sure that this is new to 1.6.  Let me run it for a while at a lower load and see what happens.

..okay, so it finished building pine whilst I was browsing the web, but when I started another pkg build, it
fell over again at a much lower load average.  I've tried getting a trace, but its a long time since I last did
this - I was expecting a list of fn calls, but I get a set of register dumps instead.  Have I forgotten to
include a symbol table or something, or have things changed?

Cheers,

David.

yes symbol support has changed because the kernels are now ELF and the
cats firmware doesn't support netbsd ELF kernels, you need to add a bit
of magic to the kernel, something like:
makeoptions     DEBUG="-g"      # compile full symbol table
options         SYMTAB_SPACE=300000

should do the trick, this embeds the symbols directly into the kernel,
rather than as an ELF section.  (note if the size isn't big enough it'll
tell you so)

ARM platforms (from /i386 mailing list)


Hello Jason,

  JRT> "/arm32" is also gone.

It's still listed on the NetBSD home page, but I see that
CATS and Shark are also listed separately, so /arm32 is  
probably headed the way of /arm26.

  JRT> Don't forget /cats, /netwinder, and /shark.

I'd given serious thought to ordering a CATS board, but the
applications I had in mind could be met by something smaller
and more simple.  I could make use of some Netwinder boards 
if I could get my paws on them.

For some projects I would need a board that I can buy off
the shelf today in small batch quantities.  It's nice that I
have a choice of vendors, but not all of them support
NetBSD.  I wish I knew enough to add support for the boards
best suited to my needs :-/

Regards,
  - Andy Ball.

/arm32 REALLY IS gone.  I deleted it myself.  The web pages must be
out of date.
