Kernel 2.6 problem on ACER Travelmate 8104WLMi

["Mirco Masa" <masa@cefriel.it>]

Hi.

I installed debian sarge with kernel 2.4 and then upgraded to 2.6
(kernel-image-2.6-686).

When I reboot the kernel 2.6 does not start. With the acpi=off option
the boot phase stacks with the following errors:

pivot_root: No such file or directory
/sbin/init: 424: cannot open dev/console: No such file
Kernel panic: Attempted to kill init!

With google search I found that this problem should due to the SATA
driver, but I don't know how to solve it.

I also tried changing hdaX with sdaX in my grub list and etc/stab but
nothing changes. 

I can load kernel 2.4, yet.

Any ideas to solve this problem?

Thanks,

Mirco
