As I am sure you are aware, there is quite a lot of changes between "minor" 
kernel series; in this case 2.6.24 -> 2.6.25.

I haven't, nor has anyone reported any such issues (via IRC, e-mail, ML or 
bugzilla) with any 2.6.25 release.

There are many fixes between 2.6.25-r4 and 2.6.25-r7.  However, without 
knowing the specifics of your hardware and lockup issues it is impossible to 
guess if any of the fixes would relate to your specific setup/scenario.

If you have not developed a hardware issue and 2.6.25-r7 displays the same 
issue, I'd suggest filing a bug with all the relevant info available.  Please 
provide a minimum of emerge --info, lspci output, and your kernel config.

Good luck.
