And I believe it has been. I have made a complete Linux install on an
USB stick of the latest Manjaro, so the stick is « setup like a hard
disk ». It will boot on other UEFI machines but will not boot on the
ProBook x360 11 G1 EE.

As a side note, this is my son's student machine, he needs it daily in
college and also often needs it at home, so I don't have it available
all day and I cannot do experiments that would break the installed
Windows (alas).

I have also been on travel between XMas and january 1st, my son at
another place with his machine, and I will be in travel again all february.

So I volunteer to perform all necessary tests to understand this issue
better, however for the reasons above it may take some time before I can
both have the machine at hand and time to work on the issue. But I will
try my best to perform all proposed tests - and already did quite a
number of them...

So far my understanding of the issue is : as soon as the computer loads
grub, it freezes, independantly of the distro, used, whether be it from
an ISO image or a "normally" installed distro, and whether grub was
directly loaded from UEFI, or chained from rEFINd.

rEFInd works, Syslinux loads and boots ; grub hangs.

Best regards.

Thank you for a notice. Sorry for late reply. I am just back after a bit
longer vacation. Now I am recovering and trying to get at speed. I will
take closer look at the thread next week.

Thanks,

May I ask you to repost the patch with suggested fixes with your SOB and CC me?
