2.6.20-rc7 killed my K410

Hi all,

I recently tried the latest git as of today and it broke badly my K410.
The last kernel I tried was 2.6.20-rc6. Git version again but this one was working fine (in UP, SMP was more badly broken than 2.6.19.1-pa0)
It corrupted the stable storage in a way that the HWversion value differs from the expected value and fails.

In my first try of booting this kernel it also corrupted the stable storage but it still reached the pdc console and I could recover it by going in COnfiguration -> DEfault. It was not possible to set any path anymore using pa pri 10/0.1 nor read any path before using this command.

Do you know a way to recover from this ?


This is the last boot attempt. For this one I disabled all CPU but the first one and palo had the nosmp option set anyway.
