Greetings, all -- Courtesy of an SL7 kernel and firmware update yesterday (yum details below), I get an eternal black screen upon booting not only the new kernel:
kernel-3.10.0-693.17.1.el7.x86_64 but also the previous one: kernel-3.10.0-693.2.2.el7.x86_64 and the one before that, as well as the rescue kernels in my grub menu So I have lost all useful access to my computer. I can, however, access the disk and all my files by mounting them from a 7.3 live install disk. My computer is an HP Pavilion desktop. The command I executed was simply: # yum update Updates other than the kernel occur automatically, and, as you can see from the above, it was a fair while since I had last updated the kernel. My system was initially installed as 7.3. I've never been quite clear, based on seemingly contradictory indications, whether it is now "on the way" to 7.4, or is already a fully qualified 7.4 system. It's whatever the automatic updates (and my occasional kernel updates) have given me. I am not competent to do much with the messages from /var/log/messages, but as far as I can tell they look more or less normal. I don't see any sign of some glaring fatal error. If someone would like me to extract a relevant subset of them, I should be able to do so. I gather that the yum updates can't be rolled back. Any advice on how to proceed from here? (This is secondary, but it would be temporaily helpful if I could chroot to the root of my filesystem from the live install DVD, and do some work. The live install disk doesn't seem to give an option of going into rescue mode.)
