Keyboard and Mouse are already taken by the windowing/console system, so Linux can obviously not get them. So it is really ok that attaching those IRQs fail, it's supposed to be like this. > The second problem is: > The Linux booting stops at /ect/random-seed to initialize /dev/urandom and > there is no login interface.

Is it right? Same question: Is your Slackware starting a login on tty1? What happens with normal Linux? You may want to disable your X for the test and check your /etc/inittab.

l4linux-2.6.22 starting
by 丁莹 07 Oct '07

07 Oct '07

Hi,everyone: Is there anybody have started the latest l4linux-2.6.22 on slackware 12.0? I do the job these days,but I couldn't start it,and the problem is strange.When I start the l4linux ,the dope is OK and the l4linux has started ,but finally the l4linux will stop with following error message: l4dope | SharedMem(get_adr): address = 0x21000 l4dope | dope: paddr=88000000 size=8000KiB l4dope | Mapped video memory at 88000000 to 00800000+000000 [8000kB] via L4IO l4dope | mapping: vaddr=0x800000 size=8192000(0x7d0000) offset=0(0x0) l4dope | Frame buffer base: 0x800000 l4dope | Resolution: 1024x768x16 l4dope | Bytes per scanline: 2048 l4dope | Current video mode is 1024x768 red=11:5 green=5:6 blue=0:5 res=0:0 l4dope | SharedMem(alloc): hl.raw=100000, id=82, size=96000 l4dope | SharedMem(get_adr): address = 0x400000 l4lx | l4lx_thread_create: Created thread 0f.08 (DOpE refresher) l4lx | l4lx_thread_create: Created thread 0f.09 (L4DOpEinput) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 14. l4lx | l4lx_thread_create: Created thread 0f.0a (IRQ14) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 15. l4lx | l4lx_thread_create: Created thread 0f.0b (IRQ15) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 12. l4lx | acquire_irq: Error attaching to IRQ 12 l4lx | l4lx_thread_create: Created thread 0f.0c (IRQ12) l4lx | l4lx_irq_dev_startup_hw: Starting IRQ thread for IRQ 1. l4lx | acquire_irq: Error attaching to IRQ 1 l4lx | l4lx_thread_create: Created thread 0f.0d (IRQ1) l4dope | atkbd.c: Spurious ACK on isa0060/serio0.

Some program, like XFree86, l4dope : might be trying access hardware directly. And I have disable the keyboard and mouse when compiling the l4linux.Butwhen I put this binary which compilered on slackware 12.0 to ubuntu 6.06,the l4linux-2.6.22 started ,and some other people have tested it on Qmenu,its also started ,my binary have put to the ftp://mirror.lzu.edu.cn/temp.Everyone who intresting in it could test it. So may be it is the problem with slackware 12.0 inittab? But I can't fix it,i am just a new both in l4linux and linux.The slackware 12.0 inittab is as follow: # # inittab This file describes how the INIT process should set up # the system in a certain run-level. # # Version: @(#)inittab 2.04 17/05/93 MvS # 2.10 02/10/95 PV # 3.00 02/06/1999 PV # 4.00 04/10/2002 PV # # Author: Miquel van Smoorenburg, <miquels(a)drinkel.nl.mugnet.org> # Modified by: Patrick J.

Not yet. This time without dope in ttyLv0 the booting log is: proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) Starting udevd: /sbin/udevd --daemon error initializing netlink socket Triggering udev events: /sbin/udevtrigger Adding 491864k swap on /dev/hda1. Priority:-1 extents:1 across:491864k Setting system time from the hardware clock (localtime). Testing root filesystem status: read-write filesystem *** ERROR: Root partition has already been mounted read-write. Cannot check! For filesystem checking to work properly, your system must initially mount the root partition as read only. Please modify your kernel with 'rdev' so that it does this. If you're booting with LILO, add a line: read-only to the Linux type 'lilo' to reinstall it. If you boot from a kernel on a floppy disk, put it in the drive and type: rdev -R /dev/fd0 1 If you boot from a bootdisk, or with Loadlin, you can add the 'ro' flag. This will fix the problem *AND* eliminate this annoying message Press ENTER to continue. But now I can't use keyboard. I have tried to make l4linux with keyboard module and without keyboard module twice. I can't still use keyboard, too. What is the matter? Cheng Guanghui

These are the sources that I've downloaded (and where I've placed them): /root/l4-linux-2.6 /root/l4-linux-2.6-env /root/fiasco /root/l4env /root/hello I want to install L4Linux creating an entry on GRUB, because I've to work also with Suse 10.2 and Windows XP (the OSs installed on my notebook), but I haven't do anything similar in my own life! My question is: how to install L4Linux? Meaning: How to compiling, building and in what order? How to modifying the GRUB bootloader to preserve my old configuration of OSs? What I would like to have is that at the boot, the bootloader ask me if I want to go in Suse, Windows or L4Linux.. Thank a lot for every suggestion you'll give me!! PS. Once that I've do all my jobs -is a research for an universitary course- can I return to have only Suse 10.2 and Windows XP? -- View this message in context: http://www.nabble.com/The-ultimate-HOW-TO-tf4192072.html#a11921435 Sent from the L4 mailing list archive at Nabble.com.
