Hi, thanks Quote:. Posted: Sun Nov 18, pm Post subject:. One thing I noticed that might be a real long shot is the boot flag is set for your root partition: Code:. BillWho wrote:. NeddySeagoon wrote:. It looks like you don't have your SATA drivers compiled into your Gentoo kernel or compiled as a module.

The line that concerns me is about half way down the screen shot you attached where it reads:. To me that screams of Gentoo not being able to communicate with the physical disk at all. As David King suggests, the culprit is most likely a missing kernel driver. Here is a list of kernel options needed to make usb mass storage work. Try to chroot into the gentoo system from a gentoo livecd as you probably know this is described in detail in the Gentoo Handbook.

There you can reconfigure and recompile the kernel again described very well in the Gentoo handbook. If you created an initramfs, don't forget to recreate it because otherwise the newly compiled kernel and drivers won't be available at boot time.

Looking over your kernel config, it looks like you enabled everything a modern system would need to boot without an initrd but you're using an older computer; I noticed in your lshw output you have an ISA bridge and a Pentium M 1. USB device discovery has been an asynchronous process for a few years now. While you may have all the drivers compiled in and your screenshot does show your USB storage device being enumerated, I suspect the kernel is trying to mount the root filesystem before the USB mass storage driver has finished initializing.

While I cannot advise you on gentoo specifics, I hope that the Debian system I use may be similar enough to help you find the right answer. In Debian, the initramfs scripts will stall the boot process until the necessary block device is available to be mounted. Sign up to join this community.

The site will show you which kernel drivers you need to select for your system.

Say your root file system uses btrfs which I definitely don't recommend but you didn't select it, or selected it to be built as a module, then you'll get the error you see. Make sure the file system support is built in the kernel. Try switching hda with sda and hdb with sdb, and Improve this answer. Nitin Venkatesh Nitin Venkatesh Hi, it passed a lot of time, but thanks. I had a faulty CD-Rom, removing that everything worked fine!

Link 1, Link 4 and Link 5 are all dead now. It's possible this error could be related to the initrd image being too large. Sign up or log in Sign up using Google.
