I applied last night's kernel / grub / shim security updates on a pair of Dell T110-II servers with UEFI boot. Now neither system will boot. After normal firmware and adapter initialization I get a blank screen and no opportunity to revert to the prior kernel (though I don't know if that would help). These systems have been running well for years & this is the first major CentOS update problem I've experienced, very frustrating! Any words of wisdom would be appreciated!!
