Hello, I run CentOS release 6.10 (Final) on a Dell Inspiron M6700. 2.6.32-754.el6.x86_64 boots, and is whaat I am running now none of these, updated ones, won't boot: 2.6.32-754.3.5.el6.x86_64 2.6.32-754.6.3.el6.x86_64 2.6.32-754.9.1.el6.x86_64 2.6.32-754.10.1.el6.x86_64 They all show the same 'symptom', grub says it is booting that kernel, screen blanks, solid corned in the left-top corner... and that's whee it stays. I know this is vague, but any ideas? thanks, Ron
