Kernel panic - VFS
I installed lfs (around the time of one of the 6.6 release candidates) on an old Compaq laptop using jhalfs. After completing the configuration (from the current 6.6 release), I tried to boot the new system and received a kernel panic saying it could not mount the root filesystem. I'll try to provide relevant details here. If any more are requested, I'll provide them. I'll give information by answering the FAQ question/answers to this question. -- Did you specify the correct partition in /boot/grub/menu.lst? I think so. The lfs partition is /dev/sda5, which is (hd0,4) on grub and (hd0,5) on grub2. grub can successfully boot grub2 from this partition. By the way, the configuration file name for grub2 isn't menu.lst any more. -- Is support for the hard drive enabled in the kernel. For SCSI this means support for the specific SCSI adapter. Yes. I specifically made sure the CONFIG_BLK_DEV_SD option mentioned in the list archive was enabled. -- Is support for the hard drive compiled into the kernel, not just as a module. (Modules are stored on the filesystem. If a driver needed to access the filesystem is stored as a module on that filesystem, well ... you know ... ;) I added CONFIG_PATA_VIA, and that did not help. -- Is support for the filesystem compiled into the kernel. Again, not a module. Support for ext2 is enabled by default, but others like ext3, reiser, jfs, and xfs are not. The filesystem is ext3, which is enabled (and is by default). I also added ext2 which isn't enabled by default anymore. I assume I missed something which should be obvious.

Perhaps you didn't enable support for the motherboards chipset or something else on which CONFIG_PATA_VIA depends? If I were you I'd enable support for lots of things that may, possibly be needed and compile them all into the kernel. Use lspci as a guide and on you host system use lsmod to see which modules it has loaded (compile them into the kernel as well). When you've got a kernel that boots, then you can start turning off options to see what isn't needed or can be compiled as a module. If you break something, back up to the last kernel that booted and try again.

Is this saying I am missing some thing in the kernel configuration or is it a permission problem My guess is it's a problem with your kernel config. Did you enable radeon drm?

Which chipset for USB?
I have given up on the NVidia chipset and trying to get a kernel built that supports USB. I am now going to buy a PCI board, but don't want to go through this hassel again. I notice NEC and VIA chipsets on PCI boards. Which is more widelt supported?

Re: Which chipset for USB?
Well, I have tried dozens of configurations to try and get my USB ports to work and nothing has succeeded. There is a config that works, because my USB ports work on CentOS, but I am tired of fighting the issue. I simply want a recommendation on a chipset or PCI board that works under LFS. --- On Sun, 3/21/10, Andrew Benton b3n...@gmail.com wrote: From: Andrew Benton b3n...@gmail.com Subject: Re: Which chipset for USB?

I have tested a lot of VIA chipsets on PCI Boards and always works fine, but i don't know about NEC Look in Device Drivers--USB Support, and there are lots of host controllers there, but the ones that you might want to enable are: * OHCI or UHCI depending on your USB controller. You can find that out by running lspci (from PCI Utils), and one of the lines should be you USB controller, and it should say either OHCI or UHCI on that line. Intel and VIA boards use UHCI, all of the rest use OHCI. These are for USB 1.1. * ECHI, for USB 2.0. Lots of devices now are USB 2.0 devices, and your motherboard should support EHCI, unless it's a pre-2004 motherboard. * xHCI, for USB 3.0. Yes, it's out there (right now, the driver is experimental), but it's not very widespread for now (the only motherboards that I know of that support USB 3.0 are very recent Gigabyte Tec. motherboards, ie: the ones that advertise USB 3.0 on the box), but if you have one of these newer Gigabyte boards, I'd say to enable it, you'll thank youself later in the future.

I have tested a lot of VIA chipsets on PCI Boards and always works fine, but i don't know about NEC Well, I went down to the local Staples and purchased a USB board. The board has NEC chips. I got rid of the errors I had been seeing with IRQs, but still no USB. BTW, as a reminder, none of my input devices work. Not even a PS/2 mouse an a serial keyboard. In even for a solution, I discovered someone who had a problem with Knoppix. IT reminded me this machine acts the same way under Knoppix, but as stated before, runs fine under CentOS. I tried using the CentOS config yesterday and it doesn't even boot up. Get a panic, so I won't persue that route. I'd be happy to get any keyboard and mouse to work. Here is a link to the Knoppix problem, where none of the input devices work: I used a Knoppix dvd that arrived with the Linux Magazine a while back. I started looking into this again because I want to bring up KDE. http://www.knoppix.net/forum/viewtopic.php?t=30497 -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
