Subject: EDD problem -- regression -- crash on booting by probing EDD

The problem below , I continued to check, and it seems really be a kernel bug (inclusively that the option edd=off don't work)

Because of this, I had to release an update of my SYS distro DVD, with i=installation using the normal 2.6.25 kernel, and a=alternatively 2.4.24-rc6-git2 what dont have that problem.  ftp://ftp5.gwdg.de/pub/linux/install/sys/  

The problem happened with an ACER Aspire 7004WSMi laptop.

=====================================================================================
There is a regression in 2.6.25.   Booting stops with: Probing EDD (edd=off to disable) message.

It dont work the kernel boot parameter edd=off .  With pci=off the computer continues to boot, but later it dont find hard disks etc.

Thats happening on 2.6.25   definitive, but was verified to go back until 2.6.24-rc6-git8, but it wasnt yet at 2.6.24-rc6-git2 which worked correctly.
