Hi !

any chance to git-bisect that further, to find the single commit which broke your kernel?

As I tested yesterday extensively, the problem wasn't present at 2.6.24-rc5-git6 (SYS \
Linux 0.17 install DVD) nor at 2.6.24-rc6-git2 (SYS 0.19) ,  but at 2.6.24-rc6-git8 \
(SYS 0.20-rc1 and 0.20-rc2) and 2.6.25 (0.21-r3).

The whole compiled packages of these kernels still are at copaya.yi.org/tgz , but I \
extracted  the important parts, see enclosed here.    The .tar.bz2 file contains  the \
config  and the protocoll of the compilation (inclusive warning / error messages). 

As you can see, the diff between the config of 2.6.24-rc6-git2 and -git8 is nothing.  \
That means: THE ERROR ENTERED INTO THE KERNEL BETWEEN THESE TWO GITs !!      

You may also analyze the error/warning messages. Please observe that the error \
message just at the beginning was already subject of another reclamation mine \
together with another person, and seems to have be corrected.

I inform still about the following:    As I make many experients and also install \
Linux often for firnds and neighbours, I see steady-steady some kernel errors, but \
have normally no time to track them, in the house of the persons.  That error here, I \
saw already several times, and never it helped the edd=off option.    Yesterday it \
happened that a friend brought a laptop (ACER Aspire 7004WSMi) to me, after he was \
unsuccessfull to install  SYS 0.21-r3 dvd with 2.6.25-rc7 . Then I tracked that \
problem during about 5 hours, inclusively trying a lot of different kernel options.  \
edd=off don't work at all, with no of the affected kernels.  With 2.6.24-rc6-git2 and \
earlier kernels the problem didnt appear, even without edd=off option, and with the \
later kernels it appears, even with edd=off .    With pci=off , also the recent \
kernels boots -- but this is useless because the system don't find any hard disk.  \
acpi=off or hwprobe=off have no influence on that problem.

Pls search that error and repair it !
**********  YOU SHOULD MAKE AN EXTRA KERNEL OPTION, WHAT IGNORES THE HARDWARE AND \
CONTINUES TO BOOT, like pci=off,  BUT WHAT DETECTS CD ROMS, HARD DISKS SATA / IDE / \
RAID , AND WHAT PERMITS TO USE THE COMPUTER NORMALLY AT LEAST IN VESA-FB OR FBDEV \
MODE !!!!! *************

As there has no other solution, I released last night SYS 0.21-r4 DVD , what contains \
both, the 2.6.25 , and alternatively 2.6.24-rc6-git2 , so that people can use them \
computer anyway / anyhow :    ftp://ftp5.gwdg.de/pub/linux/install/sys/  

I can put the suggested debug, generally, in the kernel command line of my SYS \
install DVD. However, the person gone with his laptop so that at the moment I cannot \
test it; I have to wait if the same problem occurs on another computer.
