Bugs/5.01CD

Jortega:

1) The ext2 persistent home bug (ext2 partitions not recognized properly)
is still not fixed in 5.01, because of a a typo in the knoppix-autoconfig file:
wrong: ext3|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
correct: ext2|ext3|reiserfs|xfs) MOUNTOPTS="$MOUNTOPTS,noatime" ;;
Please find a diff in here:
http://s94002264.onlinehome.us/grub/knoppix-autoconfig.diff
BTW, I found a work around fix, cf:
http://www.knoppix.net/forum/viewtopic.php?p=103883#103883
Gilles van Ruymbeke

2)knoppix splash cheatcode doesn't work, it worked with 4.0.2 version.

3)difficulty to boot on some (recent) laptop: needs to use noudev and sometimes
nompcmcia to start, but Konsole failed start, complain that no tty are available.
WORKARUND: On a PB laptop, I manage to start without passing noudev, progress bar of autoconfiguring devices don't stop but by key pressing [CTRL c] twice, boot process continue.
After an HD install, need to put rt2500usb in blacklist

4)boot process is horribly slow if a pci card with rt2500 WLAN chipset is plugged
and failed on DHCP request, no problem on Cebit 5.0: card is well recognise.

5)printing impossible (report from forums.knoppix-fr.org)

6)module compilation is not possible (out of the box), have to have a look deeply
(maybe problem with header or some links to them)
Some more info: This is probably related with the Debian [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=368544 bug #368544] as the parts missing
in the headers are those supposed to be in a newcomer linux-kbuild package

7)[INSTALL] mount with removable media,
"Please change the -u knoppix and -g knoppix in
/etc/udev/knoppix.rules, either to match the "primary user", or just
remove them."

8) CD-Burning with an external USB device is broken.
as i posted in the forum http://www.knoppix.net/forum/viewtopic.php?t=24784
there are some messages from cdrecord in the k3b failure report
about missing entrys in /dev one of them about /dev/sg0 ...
i looked for what was there in 4.0.2CD and found this:
<code>

after creating /dev/sg0 with mknod ( using mknod without beeing absolutely sure
what you are doing can lead to deleting all your data on harddisk or even worse )
at least k3b simulation started working ...
i will do a real burning test later ...

9) ipw2200 v1.1.1 (the one in kernel 2.6.17) relies on firmware 3.0 while
the Knoppix package ipw2200-nonfree only contain older firmwares.
Please update ipw2200-nonfree, cf
http://ipw2200.sourceforge.net/firmware.php

10) Setting the timezone does not work. KDE's time applet requires the root
password (should probably use ksudo instead).
Workaround: sudo vi /etc/timezone,
sudo cp /usr/share/zoneinfo/Continent/City /etc/zoneinfo.

11) Mounting of a PCMCIA flash drive works only once. After remove/insert of the card,
the following error message appears: "mount:Gerätedatei /dev/hde1 existiert nicht" (rol).

12) Improvement: the CD and DVD editions miss the p7zip package.
If you compress a tar archive of the Knoppix root filesystem, the result
is 20% smaller than the one produced by bzip2. Definitely useful!

13) Improvement: the CD and DVD editions miss the ccache package
(102 KB install size). This compiler cache is the best way to recompile
big projects (like the Linux kernel) in a much faster way.

14) To use SD cards it currently is necessary to manually ''modprobe mmc_block''.

15) Improvement: If possible include new ''ipw3945'' WLAN module.

16) I use a working CD (tested on other computers). On my computer, Knoppix stops
with the message "can't find KNOPPIX filesystem, sorry, dropping you to a (very
limited) shell..", just as the bug 15 of Knoppix 5.0DVD. Anyway the boot option
nodma does not make things work. I have found no workaround. I have got a SATA
CDROM/DVD drive (Plextor 712SA).
16b?) Can't burn, and DVD-reader access are very slow on laptop with ICH6 SATA controler
Workaround (after HD install):

''echo "options libata atapi_enabled=1" > /etc/modprobe.d/libata''

''mkinitramfs -o /boot/initrd.img-2.6.17-test''

Then modify your boot config (/boot/grub/menu.lst for grub) to adapt your initrd like:
''initrd /boot/initrd.img-2.6.17-test''

And add to your kernel options (append):

''ide1=noprobe''

17) X won't work on some systems when using Knoppix CD 5 or Knoppix CD 4.
Tried on five different systems, three notebooks, two desktop systems,
but xorg's X failed to start and complained about missing files. Integrity
of CD tested and okay.

18) In KNOPPIX_V5.0.1CD-2006-06-01-DE.iso (MD5 checked OK) *boot/isolinux/isolinux.bin
is corrupt or hash is wrong in md5sums file.

19) Apache2 returns "Partial Content" when accessing a local (127.0.0.1) page.
Small files works, larger files (> Mtu ??) not.
See http://www.knoppix.net/forum/viewtopic.php?t=25639

20)(may be the same as 1): Knoppix 5.0.1, English CD download, failed to mount the hard drives on a Dell Dimension 5100, which has a second SATA hard drive installed for backup. It worked fine if I disabled the second hard drive from the BIOS setup.
James Wimberley 9/10/2006

21) (same as 3): Knoppix 5.0.1, English CD download, failed to boot on an HP Pavilion zv5120us laptop, unmodified except for extra memory. The hangup was on the fourth line, "looking for CD in /dev/hdc". Knoppix 4.0 boots fine on the same machine. The copy of 5.0.1 should be OK as it boots on the Dell, see 20.
James Wimberley 9/10/2006

22) The !cal command does not work in a continuous manner. In fact it works about
40% - 60% of the time when done consecutively. !ls and !top work without issue, but
there seems to be a glitch in the !cal command when using the Knoppix 5.0.1 CD.

23) Notebook IBM Thinkpad T40: ipw2200 does not work due wlan-card firmware upload failure.

24) The persistent home bug: i have hdd with 2 partitions (hda1 - ntfs, hda5 - fat32). if on both partitions file knoppix.img exists, but on hda1 this file is broken(all zero) - then i can't use /dev/hda5/knoppix.img too due knoppix-autoconfig error: wenn one file was found, but broken, script will skip all other knoppix.img.

25) in autoconfig-script es is not enough fehler messages (knoppix-image: no message by broken(zero) file knoppix.img)
