Kernel_problems

River is currently booting off a PATA disk connected to a JMicron PATA controller. The current kernel is a hand-rolled 2.6.26-gentoo-r4, using the new libata driver.

The JMicron controller is picked up last, behind four LVM disks, and one new system disk, so appears as <tt>/dev/sdf</tt>.

The following kernel sources are installed

• 2.6.28-gentoo-r1
• 2.6.27-gentoo-r2
• 2.6.26-gentoo-r4

Using genkernel, with the default configuration and additional support for nl80211 wireless

When used to boot the new OS

Looks like it doesn't support UUIDs in /etc/fstab and fails to mount /var. Also get lots of errors pertaining to ext3. Possibly a corrupt filesystem.

 Could try rebuilding base OS in VMware - maybe river's current OS writes broken filesystems.

When used to boot the current OS (on a whim)

Block device /dev/sdf2 is not a valid root device… Could not find the root block device in .

Because the kernel picks up the JMicron controller first. The boot device is now <tt>/dev/sda2</tt> instead of <tt>/dev/sdf2</tt>. When booted with the right device:

Boots, but doesnt find kernel modules for the running kernel. Consequently no services start.

While attempting to rebuild the OS again in VMware, the following errors were encountered. The physical disk <tt>/dev/sda</tt> (<tt>sg1</tt>) was shared to the virtual machine.
