Re: Grub Hangs
Success! Grub no longer hangs. I reformatted the hard disk, installed Vector Linux 5.9 Light, ran zcat on /proc/config.gz, copied the resulting file to a USB flash drive formatted with the ext3 file system, reformatted the hard disk, and redid the LFS project (I took the opportunity to write some scripts to automate the process). When I reached Chapter 8.3 (Linux-2.6.16.27, which is actually Linux-2.6.16.38), I copied the configuration file from the USB stick to /usr/src/linux/.config and, at the make menuconfig step, chose from the kernel configuration menu the Load an Alternate Configuration File option. I still do not what caused Grub to hang, but compiling the kernel with the known-good configuration file solved the problem. Thank you for all your help.

After doing my homework, I have now learned how to configure the kernel using an old configuration file. I also noticed along the way that my kernel was set for an Athlon processor. I recompiled for Pentium MMX, but the problem persists, so tweaking does indeed seem tangential to it.) At least you are now one step nearer (it's pretty much guaranteed to oops on an early pentium if you optimise it for an Athlon or anything else newer than what is installed). If you don't have a known-good config, what host system did you use to build LFS ? Can you use that to derive a config which works ? Distro kernels often have initrds or similar - you need to build-in (not modules) everything which is needed to boot (particularly, filesystems and the controllers for your disk/CD (and floppy, I suppose - I didn't think recent kernels could still be booted that way). Perhaps you could go back to the host system, and use that to try to build a kernel, then copy the config over once it boots. Identifying the correct options is always a long and tedious process - the first time, you really need to look at the help in menuconfig (sometimes the help is useful), and probably build-in a lot more than is strictly necessary. Horrible thought: do you mean you compiled on a different machine ? If that's the case, there is a possibility that everything is built for the machine you compiled on (specifically, I think Pentium MMX was i586 and didn't support all the i686 opcodes, but it's been so long since I dealt with that hardware...) 3. The kernel version is 2.6.16.27. Would it be worthwhile trying Adrian Bunk's version 2.6.16.60? Is there anything I have to do to avoid a conflict with what I have done so far with 2.6.16.27, or can I simply unpack his version and follow the compilation steps as if starting from scratch? I haven't followed the details of the later 2.6.16 kernels - in general, it should be worthwhile upgrading once you have a system which boots. 2.6.16.27 itself had a degree of testing for the book, so I don't think the changes are likely to help on old hardware. For the practicalities - either use the tarball, or a patch. If you use a patch, from 2.6.16.27 you first need to revert (patch -p1 -R) patch-2.6.16.27, and then apply patch-2.6.16.60. Check the first few lines of the Makefile to confirm the version information after that - modules will install to the directory derived from the kernel version, for the kernel itself give it a different name (preferably, include the version in the name). ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
Re: Grub Hangs
l 1. When Grub hangs, the screen freezes. None of the keys, including PgUp, let me scroll up. 2. No, I don't have a .config file for the machine. (I didn't know what you meant by .config, zcat, /proc/congif.gz and make oldconfig. After doing my homework, I have now learned how to configure the kernel using an old configuration file. I also noticed along the way that my kernel was set for an Athlon processor. I recompiled for Pentium MMX, but the problem persists, so tweaking does indeed seem tangential to it.) 3. The kernel version is 2.6.16.27. Would it be worthwhile trying Adrian Bunk's version 2.6.16.60? Is there anything I have to do to avoid a conflict with what I have done so far with 2.6.16.27, or can I simply unpack his version and follow the compilation steps as if starting from scratch? Edward Why not just use the latest stable kernel? I'm using 2.6.24 with LFS 6.2 and it works well.

Grub Hangs
LFS 6.2 HP Omnibook 2100 (laptop) Pentium II (MMX) 32 MB (RAM), expanded to maximum of 160 MB using memory modules 4.1 GB (HD) 3-Com 10/100 LAN+ 56K Cardbus Modem (Floppy drive OR the CD-ROM drive connects to a plug-in module bay.) Hello, I am a newbie who has finally reached Section 9.3 (Rebooting the System) of LFS 6.2. I followed the book's suggestion to install Lynx, GPM and Dhcpcd, did the umounts, and proceeded to reboot with “shutdown -r now” As the machine shuts down, I get two messages that may or may not be part of the problem: “Stopping dhcpcd on the eth0 interface - LEASEINFO Test Failed! - dhcpcd is not running [WARN]” “No reboot fixup found for your hardware” GRUB then starts and, after printing out a few lines that I am unable to pause to read, hangs at: Call Trace: [c012bf49] get_page_from_freelist+0x221/0x28e [c012c004] __alloc_pages+0x4e/0x27e [c012c265] get_zeroed_page+0x31/0x4c [c03da534] pidmap_init+0xb/0x36 [c03d026c] start_kernel+0xe1/0x24f Code: 89 c7 b8 00 e0 ff ff 21 e0 f7 40 14 00 ff ff 0f 74 0c 31 c0 b9 00 04 00 00 fc f3 ab eb 3e e8 05 a4 f6 ff 0f ef c0 b8 40 00 00 00 0f e7 07 0f e7 47 08 0f e7 47 10 0f e7 47 18 0f e7 47 20 0f e7 0Kernel panic – not syncing: Attempted to kill the idle task! I have tried the following unsuccessful ideas: 1. Recompiling the kernel to include PCCard (PCMCIA/CardBus) support. 2. Removing the 3-Com card from the machine and recompiling to exclude PCCard support. 3. Recompiling the kernel to include Advanced Power Management (APM) support. 4. Disabling APM support in the BIOS and recompiling the kernel to not include APM. 5. Rebooting with the floppy drive inserted, instead of the CD-ROM drive. I have Googled, searched threads, etc., but am still stuck, so would be most grateful if someone could give me some ideas about what might be the problem or point me to a source of information that could help.

Thank you Edward I'm no longer familiar with 6.2, but here's my take on what is happening: Grub finds the kernel, loads it, and transfers control to it. The kernel then does something wrong which causes it to report what was happening and panic. Probably, this isn't a grub problem (we can't say for certain that grub is passing the correct detaisl to the kernel until init starts, but so far the grub side all looks ok). Perhaps, you might manage to use the PgUp key to scroll back to the start of the disagnostics ? Do you have a working 2.6 .config for this machine ? If so, did you use it for this kernel (i.e. copy it to .config, or zcat from /proc/config.gz, and then 'make oldconfig') ? Unless you can manage to identify where the kernel blew up, it's hard to know what to recommend. Tweaking the config for your hardware is good, but probably tangential to this problem. Which kernel version ? The book was released with 2.6.16.27, but Adrian Bunk has done long-term maintenance of 2.6.16 and the current version seems to be 2.6.16.60. If you aren't on a recent version, I recommend you to upgrade after you have fixed the current problem. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

I used to see it on the Intel Macs using 2.6.16 kernels or so. Essentially, the kernel didn't know how to send a reboot command for the machine, meaning you'd have to power it off manually and power it on again. IIRC, sometimes the reboot would actually succeed, even though the kernel obviously didn't think it could do it. ;) It's since been fixed (at least for the Macs). -- JH -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
