    Question How to know what is new on new kernels?

    hello, every time fedora come with a new kernel my boot broke becouse it is instaled in a raid 0 amd fakeraid so i use a custon kernel without builtin ahci module and i need to compile the amd raid module for every new kernel, rcraid module need to be upr and ahci module down to the thing work...

    I look on https://lkml.org/ at the change logs.

    Re: How to know what is new on new kernels?

    The kernel change logs can be rather verbose but will contain all the important security fixes, performance improvements and new or removed functionality. However, it's worth noting that sometimes the Fedora kernel maintainers enable/disable features that already exist in a kernel which wouldn't appear in the change logs. For example, 5.2.8 enabled CONFIG_TCG_TIS_SPI as a module which already existed in 5.2.7 but was not enabled so you may want to diff the configs as well:

    Code:
    [haydn@darkstar boot]$ diff config-5.2.8-200.fc30.x86_64 config-5.2.7-200.fc30.x86_64 
    3c3
    < # Linux/x86_64 5.2.8-200.fc30.x86_64 Kernel Configuration
    ---
    > # Linux/x86_64 5.2.7-200.fc30.x86_64 Kernel Configuration
    25c25
    < CONFIG_BUILD_SALT="5.2.8-200.fc30.x86_64"
    ---
    > CONFIG_BUILD_SALT="5.2.7-200.fc30.x86_64"
    4001c4001
    < CONFIG_TCG_TIS_SPI=m
    ---
    > # CONFIG_TCG_TIS_SPI is not set
    [haydn@darkstar boot]$
