Subject: MGA G200 issue in 6.12 and up
Date: Wed, 9 Apr 2025 12:58:05 -0400	[thread overview]
Message-ID: <Z/anHRAx3SQWr+h8@animx.eu.org> (raw)

I decided to upgrade to 6.14 on a system with a Matrox G200 onboard vga
(supermicro X9SCL).

I use this system via the BMC.  When the mgag200 driver loads, the bmc
screen flashes between no signal and the screen.  The rate seems to be about
1 second no signal and 1 second with signal.

6.12 and 6.13 both have this problem.

6.11 does not have this problem.

I have a monitor plugged into the vga port and it doesn't have this problem
on any of the kernels I've tried.  Only the remote connection through the bmc
has this problem.  I have booted the system with and with out the monitor
plugged in, it does not appear to make a difference.
