You are running on a 64kb PAGE_SIZE kernel. The default kernel
|
|
switched to 4kb PAGE_SIZE which will prevent it from mounting btrfs
|
|
or the swap partition.
|
|
|
|
To ensure that your system still works, I am refusing to install
|
|
this kernel. If you want to force installation regardlesss, reinstall
|
|
with the environment variable FORCE_4K set to 1.
|
|
|
|
To stay with a 64kb PAGE_SIZE kernel, please follow these steps:
|
|
|
|
$ zypper in kernel-64kb
|
|
[ reboot into the new kernel ]
|
|
$ zypper rm kernel-default
|
|
|
|
You will then be on the 64kb PAGE_SIZE kernel and can update your
|
|
system normally.
