Description José Jorge 2019-05-21 14:25:49 CEST
We have 3 ESXi 6.0 hosts running VMs. In two of them, Mageia works nicely. In the last, it stops at boot. I join the dmesg read through a virtual serial port.

Mageia 7 has the same problem.

It seems a FPU problem as far as I understand the dmesg.
Comment 3 Thomas Backlund 2019-05-22 13:51:45 CEST
I wonder if the ESXi is exposing a cpuid flag that the underlaying Xeon Silver 4112 is not providing...

Can you provide the log from Cauldron with kernel-5.1.3-6 or later.

Also, you can try to boot with "noxsave" on kernel command line

You got it, we were in U1... it boots nicely with U3 in this hardware.
