Bugs/3.8.1
List V3.8.1 bugs here
1. No USB keyboard support on Dell Optiplex GX280. (SOLVED)
Some hardware details:
* USB Keyboard: Happens to be a Danish keyboard, shouldn't matter. * SUSE identifies the keyboard as "Dell USB Keyboard Hub" and uses the hid driver * USB Mouse * Pentium 4 * SATA hard drive
symptoms:
* Keyboard works at the "KNOPPIX: " boot prompt, anything after that it doesn't * above the "Welcome to KNOPPIX... (etc)" white text line, you have: 1. image of tux 2. audit(somenumber.???:?) 3. ata2: disabling port it's that 3rd line that perplexes me. * Hangs 30 seconds into booting, immediately after message: "2.78 Knoppix booting" * It seems it never detects anything USB (though the USB mouse kinda works later...) * booting "debug" asks to type exit to continue... nothing responds on the keyboard * booting "failsafe" makes it all the way to KDE where the mouse (mostly) works, but the keyboard does not. * booting "expert" fails when it needs KB input to select SCSI drivers. * booting the {nousb|nousb2|lang=da} all fail. * booting "knoppix testcd" fails similarly * booting "failsafe testcd" tests the CD and makes it into KDE as prev. mentioned
ideas:
* ?? I've tried a lot of tweaking and some searching, anyone experiencing similar issues? * Is anyone having success with 3.8.1 and a new Dell?
solution: booted with "knoppix acpi=off" and all was well. Apparently this Dell gx280 uses a 'difficult' power management ... chipset (likely the wrong word.)
suggestion: list acpi=off in the F3 list of boot parameters, it's more pertinent than some of the others that made the list.

With knoppix 3.8.1 (english) on an IBM x335 machine and console attached via a console chain cable the keyboard becomes inoperative after Knoppix has booted. After the CPU tuxes the following lines are written to the console:
i8042: Can't read CTR while initiating i8042 ide2: I/O resource 0x1E8-0x1EF not free ide2: ports already in use, skipping probe
This did not happen with Knoppix 3.4 (english). Just to let you know. For further information please write: jvwCHANGETHISTOATSIGNiwr.fzk.de
3. Typo
If you open K Menu -> KNOPPIX -> Utilities you will see "Chose/Restart KNOPPIX Desktop." That should read "Choose/Restart KNOPPIX Desktop." Just a small typo, but it seems to have escaped the developer's watch in the last few releases.
4. USB2.0 Storage device slow speed
[CLH] USB2.0 external hard disk is auto-mounted as ub device, which is using USB 1 transfer speed, far slower than using sd_mod. for example, trying to mount /dev/sda1 gives error because module sd_mod is not available (modprobe sd_mod gives error) should recompile kernel with scsi module (sd_mod) support. Also check out the usbmount http://usbmount.alioth.debian.org/ which automount external USB storage devices , I tried Ubuntu liveCD and it worked well at USB2 speed.
5. Keyboard not working after loading
Hardware Details:
*Dell Latitude D610
Error Messages:
*i8042: Can't read CTR while initiating i8042 *ide2: I/O resource 0x1E8-0x1EF not free *ide2: ports already in use, skipping probe
After that point it seems the keyboard is non-functional. Touchpad/eraser are not functional either. Doing a "shutdown" will get to the point of "eject CD and hit return" keyboard still not functional. Worked fine in English V 3.6. USB Mouse works.
have you tried the acpi=off boot parameter? our machines may share a similar (Dell) issue.
6. Can't find KNOPPIX filesystem. sorry.
Hardware:
*Sony Vaio N505SN laptop *PCMCIA CD drive
Boots fine, starts searching for hardware:
*Scanning for USB/Firewire devices...Done *Enabling DMA acceleration for: hda
Then fails with "Can't find KNOPPIX filesystem. sorry.", and drops into a mini-shell. I tried the "ide2=0x180 nopcmcia" boot options, but no joy.
