Comment (by pulkomandy):
Hi,
Today I tried using the userlandfs with cdda to see if I could reproduce
the crash in Userland. But instead I still got to KDL.
Here is what I did:
Compiling:
{{{
jam -q "<userland>cdda"
cp cdda ~/confiig/non-packaged/add-ons/userlandfs/cdda
}}}
Running:
{{{
pkgman install userland_fs
/system/servers/userlandfs -d cdda
}}}
Mounting (make sure to disable automatic mounting in Tracker prefs to
avoid any confusion):
{{{
mkdir /audiocd
mount -t userlandfs -p cdda /dev/disks/scsi/0/1/0/raw /audiocd
}}}
You can then rip the CD and unmount as usual. cddb seems to not work here
in that setup. Things went fine until the first CD with cdtext, which
triggered a KDL in malloc called from userlandfs.
If this is the same bug, it means it is not an issue directly in the cdda
code (that would have crashed on userland side). It can be a problem in
the ATAPI commands and the way they are handled by the SCSI driver, or
some issue somewhere in the VFS or disk/partitioning system.
