Message-ID:  <>

I have a problem with the 5.0 GENERIC kernel from the miniinstall
ISO image.

Please note: I'm not subscribed to this list, so please reply to me.

Download time was Jan. 20 from

For installation I used the GENERIC kernel from the CD,

MD5 (boot/kernel/kernel) = 0441abf2a9970e24cbd856cf89fa32a1

During the boot process the system hangs and with 'boot -v' I get the
following page-fault (I was only able to include the last lines of the
boot process.):

Here is also the dmesg.boot from 4.7-STABLE currently running on the
machine, so that you can see the devices on the laptop.
