It is probably easily reproducable. Now I just need an NTFS image to
test it with :-)

The umount code is probably forgetting to dereference the mount point
in either ntfs or msdosfs, and this likely causing the panic.

Oh, another question in addition to my last question... were you
CD'd into either the ntfs or the dos filesystem when you rebooted?
Does the problem still occur if you are CD'd into / when rebooting?

Heh. If people keep on posting JPGs I'll start asking for you all to
install ImageMagic and use the 'convert' utility to reduce the quality
of the JPGs to make them smaller :-)

If you unmount the fat32 filesystem before rebooting, it doesn't
generate the panic, right?

Unfortunately, I was unable to reproduce it at all :(
I think that just before I rebooted i tried to copy a dvd image to the
fat32 file system, and after copying 4gb it say the file is too large,
so i deleted it, but thats about it.

Btw, can the 4gb limit be removed?

The sole reason why i had to move a dvd image was because i have been
unable to burn dvds in DragonFly for a long time. I used to use
growisofs in linux but for some reason the program write a couple of
bytes and then exits, practically fucking up the dvd. dvdrecord has the
same problem as cdrecord, it cant find the SCSI subsystem

elevator# cdrecord -scanbus
Cdrecord 2.00.3 (--) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No local SCSI transport implementation for this architecture.

I'd be happier if i could start buring dvds than having to move them to
fat32 and burn from windows.

Thanks a lot,
Petr

Petr i was looking at your post in Bugs, about your inability to burn
dvd on dragonfly. I think you are using the wrong cdrecord version, the
one that comes with iso. My suggestion is to uninstall it and install
cdrtools-ossdvd from pkgsrc.

dvd+rw-tools is what I use, which has a dependency on cdrtools-ossdvd.
growisofs, from dvd+rw-tools, seems to burn DVDs just fine.

#7 Updated by elekktretterr almost 8 years ago

Thanks Ezra and Justin. I installed sysutils/cdrtools-ossdvd after
uninstalling sysutils/cdrtools and now it detects my dvd recorder :) Im
installing growisofs now to test it again and will post an update.

It would still be nice if the 4gb size limit was removed though,
especially now when dvd's are pretty much standard for everything except
audio.

Doesn't ISO9660 limit maximum filesizes to 4*2^30 bytes? Same goes for
FAT32 btw, afaik.

has this been solved?

#11 Updated by elekktretterr over 7 years ago

The problem wasnt solved because none of us can reproduce it.

#12 Updated by alexh over 5 years ago

If it's not reproducable we can close it.
