Kevin,
The assert I suggested in your recent scsi-disk patch series has
triggered. I need to study the scsi-disk.c code more to understand
how to solve this.

Hi Nigel,
Is there a disk image available to reproduce this bug? I searched for
Debian SPARC 2.4-based disk images but wasn't able to find one.
If it's not easy to share your disk image, could you please test this
QEMU tree which backports the assert:
http://repo.or.cz/w/qemu/stefanha.git/shortlog/refs/heads/scsi_assert
You can grab the code like this:
git clone -b scsi_assert git://repo.or.cz/qemu/stefanha.git
If the assert triggers in that world then data corruption was
previously possible but hidden (a SCSI request has a one data buffer
and concurrent reads are being issued to the same buffer!). This
would mean an existing bug that needs to be fixed has been exposed.
If the assert doesn't trigger, then the issue was introduced recently
and we can dig more into that.
Thanks!
Stefan

I got the image http://wiki.qemu.org/Download. It was sometime ago and
it may no longer be there - the image on that site now mentions Sparc
2.6, I guess 2.4 has been removed.
I have no means for you to take a copy of my image. Sorry.

Will do - thanks for making it available. It may take me a bit of time
to get around to it, but I will do so as soon as I can.

That retrieves a directory called scsi_assert which is empty. Are you
expecting that? Should I therefore use the directory in there called
stehana?

Yes, 'stefanha' is the source tree directory.
When I do that git clones to a directory called 'stefanha', which
contains the QEMU source tree from the scsi_assert branch. But you
can also use following alternative if your git version does not
support -b <branch-name>:
git clone git://repo.or.cz/qemu/stefanha.git
cd stefanha
git checkout origin/scsi_assert

I just gave the SPARC Linux 2.6 image from qemu.org a spin on sun4m but no luck:
sparc-softmmu/qemu-system-sparc -kernel
'/tmp/sparc-test/vmlinux-2.6.11+tcx' -initrd
'/tmp/sparc-test/linux.img' -append "root=/dev/ram" -drive
if=scsi,file=test.raw,cache=none
The kernel correctly notices the sda device and detects partitions (so
it is doing disk reads). There is no assertion error so this problem
may be specific to the Linux 2.4 ESP driver.

At least Gentoo 2004.1 (Linux 2.4.25-sparc-r1) live CD works.

I built your tree - it does not trigger the assertion. Linux/sparc/2.4
boots and seems to run fine.
Thanks for your help.

Thanks for testing. This narrows down the problem to just a few commits.
Would it be possible to share your the kernel image (vmlinuz) and
initrd file? That's all we need to reproduce the bug.

Sure - how do I create them from the Image file I have? (I don't use an
external kernel image and initrd file to boot)

Sadly that doesn't work:
njh@compaq:~/qemu/sparc$ /sbin/fdisk -lu debian.img
Disk debian.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk debian.img doesn't contain a valid partition table
But, it has occurred to me, - I boot using your code and get
/boot/vmlinuz and /boot/initrd.img that way. Would that be OK?

fdisk doesn't like the SPARC partition table. I used to have tools to
deal with this but have forgotten which ones they were.

Thanks for providing the kernel and initrd. Unfortunately I wasn't
able to get them far enough to trigger the assert. More on that at
the bottom of this message but in the meantime I looked over the
relevant commits and spotted an issue with the assert.
Please try this branch:
http://repo.or.cz/w/qemu/stefanha.git/shortlog/refs/heads/scsi_assert_moved
That branch contains a small code change that moves the assert later
into the read code because we're doing the assert too early.
Hopefully this fixes the issue for you.
Regarding the kernel and initrd, I'm unable to get it far enough to
fsck, which is where you hit
the assertion. Either kernel parameters need to be set or the image depends on
a root filesystem (which I don't have).

I tried lots of different ways to get your code, but failed. The one
closest to the instructions that you gave me last time failed with this:
njh@compaq:~/tmp/foo2$ git clone -b scsi_assert_moved
http://repo.or.cz/w/qemu/stefanha.git/
Cloning into stefanha...
warning: Remote branch scsi_assert_moved not found in upstream origin,
using HEAD instead
warning: remote HEAD refers to nonexistent ref, unable to checkout.

Try:
git clone -b scsi_assert_moved git://repo.or.cz/qemu/stefanha.git
Sorry for that. You can get the repo clone info by clicking
"qemu/stefanha.git" at the top of the
http://repo.or.cz/w/qemu/stefanha.git/shortlog/refs/heads/scsi_assert_moved
page, the git:// URI is usually the best one to use.
