I should have read the undelivered message better: ``` <dalias@libc.org>: host brightrain.aerifal.cx[216.12.86.13] said: 550-Message blocked for policy reasons: 550-Your mail system is forging its hostname. 550 Message could not be delivered (in reply to end of DATA command) ``` I got the same for dalias@aerifal.cx. No idea, what is supposedly wrong with our setup: $ host mx.molgen.mpg.de mx.molgen.mpg.de has address 141.14.17.8 $ host 141.14.17.8 8.17.14.141.in-addr.arpa domain name pointer mx.molgen.mpg.de. Kind regards, Paul

Commit 62d89a7d49af ("video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen") accidently decreases the maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB by missing one zero. This caused the driver initialization to fail with the messages below, as the minimum required VRAM size is 2 MB: [ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected [ 9.444502] matroxfb: cannot determine memory size [ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1 So, add the missing 0 to make it the intended 16 MB. Successfully tested on the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is gone. While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned properly. The value could probably also be increased from 8 MB to 16 MB, as the G200 uses the same values, but I have not checked any datasheet. Note, matroxfb is obsolete and superseded by the maintained DRM driver mga200, which is used by default on most systems where both drivers are available. Therefore, on most systems it was only a cosmetic issue.
