After apply a fix to 46D kernel, I have this error :
'OS release OS400 V5R3 M0 is not supported with this kernel (46D)'
'Severe problems were detected during initial system check.
Please, do not use that system before fixing these problems
For instance I apply ML patch 22 for Internet Mail Gateway.
Thank you for your help
