Hello!
Just wanted to report of the following problems:
Compile Problems when selecting the following:
- Selected PCMCIA-SCSI
- Selected Framebuffer -> Aty128fb
- Sound / trident.c
Other bugs:
- devfs init is still missing -> /dev/vc/0 is the only console.
- floppy driver still broken
- ntfs sometimes crashes the system: working on a loopback file caused
ntfs to report corruptions in the file system and this hangs system
completly.
If you need more informations, just tell me. Currently I've some time
to debug parts of the kernel.

I am interested in this ntfs report. Which way round was the loopback file?
I.e. did you mount: mount -t ntfs -o loop somefile_on_a_non_ntfs_partition
or did you mount: mount -t some_file_system -o loop
somefile_on_an_ntfs_partion?
Can you send me the errors produced? If there is an oops, please decode and
send it, too.
Also it may be useful to have the debug output from ntfs (depending on what
the errors/oops say - they may be sufficient to pinpoint the problem), i.e.
enable debugging when configuring the kernel, and then as root do: echo 1 >
/proc/sys/fs/ntfs-debug. Note this will absolutely flood you with debug
output so the system will run slow as hell... So it is best to only enable
debug messages just before the error occurs if that is possible.
Thanks,
Anton

Been broken. A new driver is being worked on.

Ug. That is partially fixed. I did get the other vc/X but only root can
access them. I have to talk to linus about the best solution here.

good to know. I don't use it anyways, just wanted to report.

btw, this fb driver seems to be really experimental or beta, as it does
nothing when loading on a mobility chip.

What about the patch with con_init_devfs(); ? Isn't that simple and stupid
enough to use ? [this is the only way I can work with those kernels right
now..]

mount -t ntfs -o loop file.sav-on-ext2-or-on-xfs[when using 2.4.18] /mnt

The test I did was the following [may I call that test ?]:
cd /mnt; mkdir /ntfs_on_ext3; cp -r * /ntfs_on_ext3
While copying, with or without debug, the system hangs, but top only reports
7 % cpu load.
Copying the files results in a input / output error.
It has never been an oops and actually 2.5.29 does _not_ hangup anymore!
Still it stops to copy the files and aborts.
I am currently retrying with debug enabled...

oops. forget that above. Oh yes, ntfs is really reporting much.
You can find the output at ftp.schottelius.org:/pub/tmp, it's about
600k compressed.
I am really happy that this time the cp did not hald my system!
Nico
p.s.: what was the maximal file size on ext3 ? I just gunzipped a 4gb
file (the ntfs image the whole story is about), which could not
be transfered through scp/ftp in this size...

Where is it? It doesn't appear - I just looked...

Sorry not sure. I think it is dependent on the fs block size you use...

Try my patch now and tell me how it works.

I though i just cp'ed it...but I forget to move it from my home..
now you'll find it.

Btw, ntfs does not compile in 2.5.30 anymore. Neither with or without debug.

Btw, it was not a NTFS problem, just watched wrong!
It seems to be a general problem in the fs tree with devfs.
I am currently applying the console patch, but this doesn't fix the
error I posted in the last mail.
If I have some more time, I will try to fix it myself...

I don't think the hangs had anything to do with ntfs. The io errors, I was
able to reproduce on 2.4.19+ntfs but only when accessing compressed files.
I have fixed this in the latest ntfs, at least the errors I saw are gone.
Could you give it a try and let me know if it solves your problem, too?
You can download by pulling from bk://linux-ntfs.bkbits.net/ntfs-tng-2.5 or
by applying the patch I sent to LKML last night. I can forward it to you if
you need it...
btw. I think it was compiler problem, so out of interest, which compiler
are you using? I was using gcc-2.96-RH7.3-latest...
Thanks,
Anton
