So I can see the output on all configurations.

The state is now:
1) Linux-conf  x86-ux_defconfig without mag : runs
2) Linux-conf  x86-ux_defconfig with mag    : runs
3) Linux-conf  x86_rw_config  without mag   : runs
4) Linux-conf  x86_rw-config  with mag      : error

My x86_rw-config is in the Attachment.
The error is:

attempt to access beyond end of device
ram0: rw=0, want=4764729332, limit=8000
Buffer I/O error on device ram0, logical block 2382364665
attempt to access beyond end of device
ram0: rw=0, want=4606413050, limit=8000
Buffer I/O error on device ram0, logical block 2303206524

Attachement log_ioerror ist the whole output.

Why this IO-Error ?
Does something overwrites the ramdisk ? Or is the ramdisk shortened ?

I give in qemu 1024M and Linux in the cmdline 128M,but the phenomenon is still there.

Thank you very much
