OpenBSD snapshot packages crashing on my HP ProLiant ML310e Gen8 v2

[J65nko]

In 6.9-beta Firefox browser tabs keep crashing I reported crashes from firefox as well as firefox-esr. I can add the following to the list:

• librecad-2.2.0rc1p1
• libreoffice-7.0.5.2v0

This was using

dmesg | head -3
OpenBSD 6.9 (GENERIC.MP) #467: Thu Apr 15 14:05:19 MDT 2021
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

My ProLiant uses a built-in Matrox VGA chipset :

[    53.628] (II) MGA: driver for Matrox chipsets: mga2064w, mga1064sg, mga2164w,
        mga2164w AGP, mgag100, mgag100 PCI, mgag200, mgag200 PCI,
        mgag200 SE A PCI, mgag200 SE B PCI, mgag200 EV Maxim,
        mgag200 ER SH7757, mgag200 eW Nuvoton, mgag200 eW3 Nuvoton,
        mgag200eH, mgag200eH3, mgag400, mgag550

and

$ dmesg | grep -i VGA
vga1 at pci7 dev 0 function 1 "Matrox MGA G200eH" rev 0x00

To rule out a X Window problem with that chipset I tried to install an PCI-X VGA card but, this card is not recognized by OpenBSD. (In an older Proliant that card worked IIRC)

The good news is that iridium-2021.03.88 works

I left some space for Linux on this disk so in order to use Libre-Office I will to have install Linux Mint, but I hate to deal with Grub ......
