Guys,

[rfu@appone aic7xxx]$ uname -a
Linux appone 2.4.3-12smp #1 SMP Fri Jun 8 14:38:50 EDT 2001 i686 unknown
distribution is RedHat 7.1
meanwhile I encountered another strange thing related to this:
at home I've got a rather old ASUS socket7 EISA dual board (T55P2D4-Dual).
I installed RedHat 7.1 on a different board (T55P2D4, no dual) on an old
2 GIG IDE disk, moved the disk to the dual board, tried to install
the SMP kernel and got the same error:
copy big file (about 12 Megs), diff both (original and copy) and they are
different :-( the only common thing in this case is RedHat 7.1 !?
regards,
rainer.
