Subject: [386bsd] can't mount cdrom after PK-0.2.3
Message-ID: <gjung.736550797@guug.de>
Summary: Error in mounting the cdrom after installing patchkit-0.2.3

I have installed patchkit-0.2.3 and now I can't mount my cdrom anymore.
If I try a "mount -r -t isofs /dev/cd0d /cdr", I only get the message
"mount: Read-only filesystem" and, after accessing the root (eg with
'ls /'), the system hangs.
I have searched 'kern/vfs_syscalls.c' and 'isofs/isofs_vfsops.c' for
the problem and it seams that isofs_mount gets completely wrong
parameters.
I have inserted print-statements like
printf("isofs mp=%x dir=%x data=%x ndp=%x p=%x\n",mp,path,data,ndp,p)
as the first statement in "isofs_mount" and just before "VFS_MOUNT"
in "mount" and I get the following output:
vfs: mp=fe2b3x00 dir=fdbf9015 data=fdbeefd4 ndp=fdbfff0c p=fe2e9200
isofs: mp=fe2e9200 dir=fdbfffa4 data=fdbfff9c ndp=fdbef000 p=5
Note the value for p at vfs and for mp at isofs is the same.
Mounts to ufs are ok, I have not tested nfs, mfs and pcfs.
Maybe this is a known bug and someone has solved the problem.
Please reply be email, as I can't read the news regularly.
