 i386
Architecture: i386
Machine: i386
>Description:
    Using an ident longer than a certain length in an i386 kernel config
    file (which is otherwise pretty much GENERIC) causes the uname
    system call in that kernel to fail with "cannot allocate memory."
>How-To-Repeat:
    Add this line to your kernel config:

        ident "4-PROD-NOXEN-MP $Revision: 7280 $ $Date: 2008-08-14 19:01:43 
+0900 (Thu, 14 Aug 2008) $"
