I am using grml for testing purposes on many different servers, I am using the standard ISO with your netboot files, in addition only a little netscript for mounting nfs shares. With current version "2014.11" I recognized that all Supermicro boards with onboard VGA "Matrox G200eW" fail to boot completely. On local monitor I can only see "populating dev", nothing else, not possible to switch terminals.
But remote connection with ssh is still working then. So I find error messages with dmesg and syslog:
[ 39.700307] checking generic (f9000000 180000) vs hw (f9000000 1000000)
[ 39.700310] fb: switching to mgag200drmfb from simple
[ 39.700335] Console: switching to colour dummy device 80x25
[ 39.700590] [drm:mga_vram_init] *ERROR* can't reserve VRAM
[ 39.700592] mgag200 0000:07:04.0: Fatal error during GPU init: -6
Sorry for my incomplete, unprofessional bug report, I am not a developer or something like that...
If you need any further information please let me know.
Thank you for GRML!
