ia64 and powerpc support crash dump too?

OK. There is a server now at git://newgolddream.dyndns.info/ though I am
having a lot of problems getting gitweb to work.

As an aside: was really surprised at how hard git hammers on the
server's resources.

I have been hosting my SH stuff on CVS so far. It is just a place where
I can go to when I need to roll back mistakes, though it is also public
on the web for a variety of reasons, not least because it allows me to
look at the sources in a browser when away from home.

I'd like to move to doing this with git - anyone care to recommend a git
web interface as there appear to be a few of them around.

[PATA/LIBATA] No init found / init=/bin/sh failure

From: Kristoffer E. <kri...@gm...> - 2007-10-24 16:50:32

Jeff any libata changes that might explain this?

I've been bugtracking this the last couple of days, but getting nowhere.
Same configuration was working less than a month ago. It uses pata_platform.c which in turn registers an ata device.

This segment looks just as it usually does.

Any suggestions on how to bugtrack this, setting init=/bin/sh doesn't do anything.

[patch 2/2] Use BOOTMEM_EXCLUSIVE for kdump

From: Bernhard W. <bw...@su...> - 2007-10-24 16:37:41

This patch uses the BOOTMEM_EXCLUSIVE, introduced in the previous patch,
to avoid conflicts while reserving the memory for the kdump carpture kernel
(crashkernel=).

[HP6XX] - no init found (PATA issue?)

From: Kristoffer E. <kri...@gm...> - 2007-10-21 19:58:28

Greetings,

i've got a new set of troubles, which I find hard to bugtrack. Partitions are detected properly but for some reason fails to boot.
This problem arose after syncing with linux-2.6.git a week or so ago. Old userlands which have worked fine in the past doesn't anymore (the /bin/sh issue is somehow wrong).

Ive noticed alot of libata problems, this one of them?

Best wishes

We plan on use these timer interrupts to drive the alsa sounddriver. But you are quite correct, I'll resubmit these
as soon as the alsa driver is finished.

[PATCH] Use BOOTMEM_EXCLUSIVE for crashkernel reservation

From: Bernhard W. <bw...@su...> - 2007-10-19 14:52:28

This patch implements the usage of BOOTMEM_EXCLUSIVE for crashkernel
reservation on other architectures. The only architecture that applies
is sh.

The patch is based on current git tree plus
kexec-introduce-bootmem_exclusive.patch from -mm tree.

There's nothing that uses these, so why are you adding them? If you plan
on hooking these up in the hd64461 or TMU code, submit these definitions
along with the code that uses them.

[PATCH / HP6XX] : Add Timer values into HD64461.h

From: Kristoffer E. <kri...@gm...> - 2007-10-18 19:39:00

Attachments: hp6xx-hd64461.h-tmu-values.patch

Greetings,

Shortlog:
This patch adds HD64461 Timer adresses & registers to the HD64461 header file (/include/asm-sh/hd64461.h).
The timers (TMU0 & TMU1) can hold 16bit values and auto loads the counter constant when it
reaches zero. Upon reaching zero it generates an interrupt.

SH2, SH3, and SH-X3 won't be impacted by it, the changes in question that
are causing the problems are purely issues on aliasing SH4 caches.
Curiously it only seems to be popping up on systems with 2-way set
associative D-caches.

[PATCH] ALSA - protect Dreamcast PCM driver (AICA) from G2 bus effects

From: Adrian M. <lkm...@gm...> - 2007-10-17 20:30:29

The G2 bus on the SEGA Dreamcast connects both the maple peripheral
bus and the AICA sound memory. DMA requests on one can cause the other
to timeout on memory operations.

This patch prevents maple interrupts from causing hiccoughs in the
AICA sound (maple bus code will land in 2.6.24).

There are other cleanups for this (AICA) code - but this is in effect
a regression fix rather than a cleanup.

i'm seeing random crashes on my lantank running 2.6.23 ... rebooting into=20
2.6.16.xx works fine.

that has a SH7751R with 2-way caches in write-back mode ... havent had time=
 to=20
try the suggestions above though :/

7760 with "standard" config: write-back, direct-mapped disabled, no SQ, no
OCRAM.  Haven't tried WT; kernels with WT used to never boot. I'll give it a shot.

What CPUs are you running on, and what sort of cache configuration are
you using? Presumably write-through caching also works fine?

I don't experience any breakage on a 4-way d-cache, but there have been
problem reports on other CPUs with 2-way. Specifically it seems to be a
cache colouring problem, bumping up the page size also corrects the
issue.

I'll see about reproducing and debugging it on a 2-way dcache..

2.6.23: random segfaults

From: Manuel L. <ma...@ro...> - 2007-10-16 11:52:45

Greetings,

With 2.6.23 my board(s) are again experiencing random segfaults and
pipe failures (compilejobs randomly abort with bash segfaulting
and/or gcc/make stop with "too many commandline options" errors, ...)
I tracked it to these two commits; reverting both stabilizes the system
again:

sh: Reclaim beginning of P3 space for vmalloc area
 http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=f0b859e3d63a07995f0db294864c2f3c9228f1e4

sh: Add kmap_coherent()/kunmap_coherent() interface for SH-4.
 http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=8cf1a74305688c85fc8d23ab7432a0c447ee6413

Thanks,

Now that the ax88976 changes have been merged via the netdev queue, I've
applied the board parts. This will be in my second merge for -rc1.
