I've got a raid0 partition (2*100Go) that is correctly mounted by 2.5.44 but 2.5.45 compiled with the same configuration gives me that:

3 warnings issued. Results may not be reliable.
my raid partition is from two hard drives hde and hdg plugged with hpt370 chip (included in compilation) I also patched arch/i386/Makefile to use gcc-3.2 -march=athlon-xp option.
Thanks in advance
