[coreboot] Freeze after few bootups

[i1w5d7gf38keg at tutanota.com]

Hardware: gigabyte g41m-es2l, coreboot git, seabios-git, native vga

I have the problem that the computer is freezing after few boots. Its hanging then at every boot in this stage:

....
				
        tWR:  5

        tRFC: 35

        tWTR: 4

        tRRD: 3

        tRTP: 4

Channel 0 possiblynot in self refresh

Channel 1 possiblynot in self refresh

Done clk crossing

Done launch

Done timings

DimmA populated onlyin channel 0

No dimms in channel1

Done ODT

Done pre-jedec

MRS...

CH0: Found Rank 0




Nothing happens afterwards.


I replaced the RAM to an other one. Turned it on, it then reset once:
....
				
        tRAS: 18

        tRP:  6

        tRCD: 6

        tWR:  6

        tRFC: 51

        tWTR: 4

        tRRD: 3

        tRTP: 4

Reset...



and hangs again at this stage:
...
				
Done ODT

Done pre-jedec

MRS...

CH0: Found Rank 0

I disconnected the PSU, removed the CMOS battery and wait few minutes. Then it stops hanging at this stage.

I had this problem also on an other g41m-es2l mainboard with latest libreboot image installed. So it does not seem to be hardware related and not fixed in latest coreboot.

Anything i could do to help fixing this bug?
