I hope this does not offend if it's not posted in the correct forum, but I did not find anything more appropriate...
OK, I updated to Kernel 126.96.36.199-0.1 (desktop) using the online actualisation (Updater Applet). It installed the kernel OK, but the initrd seems to be broken: After a restart the PC got stuck just after "GRUB" and I landed in the mini-shell.
The kernel resp its initrd was not able to load from an ext4 root partition.
After lots of rebooting using the original kernel and checking ... too long a story. Then I re-did the "initrd" just by running "mkinitrd" again, after that I was able to successfully boot again.
Did anybody have a similiar experience ? Is it possible that the official "initrd" of kernel 188.8.131.52-0.1-desktop is broken ?
