ISDN security ???

[Felix Triebel]

Hello,

when compiling the kernel 2.4.18-pre7, I get the following messages:

md5sum: MD5 check failed for 'isac.c'
md5sum: MD5 check failed for 'isdnl1.c'
md5sum: MD5 check failed for 'isdnl2.c'
md5sum: MD5 check failed for 'isdnl3.c'

What does this mean? Is the ISDN driver corrupt?
Everything works as usual, but this messages make me worry about security!
Is this a known problem? Could someone explain it to me?

kernel messages when loading the modules:
