Comment 2 for bug 152820

2.6.22-14 has rendered my PC unbootable too. This is true for both i386, and AMD64 flavors of the kernel.

The problem appears when it tries to load the ide drivers for the disks I have. Modprobe exists abnormally,
and there's no ide support, so can't be booted. The kernel dumps to busybox.

There are a bunch of messages. The first, which seems a bit unrelated as it is a bit further up the log is:

[xxxx] BUG Unable to handle kernel NULL pointer dereference at virtual address 000000000

A bit further down we have modprobe trying to insmod ide_disk but fails, and exists anormally.

Stacktrace given:

[xxx] ide_in_drive_list 0x45/0x80 [ide_core]
[xxx] idedisk_check_hpa [ide_disk]

The stacktrace continues and I can add more if its needed (gotta do it by hand)
