Don't know what swap looks like (try "swapon" to see). If it's a partition (like "dm-1" or something), that's not it, either. > so this still would leave something like 40GB missing. Yup. It is odd. I've never seen anything like this unless you have something weird starting up early in the boot process. Perhaps a device driver that's got weird stuff in its configuration and is part of your initramfs. Do an "lsmod" and see if one of the modules listed is using a boatload of memory. If so, then check the /etc/modprobe.d/* file for it and see if there's something odd in there. > I opened up a bug on the kernel tracker at > https://bugzilla.redhat.com/show_bug.cgi?id=1593878 Yeah, that might be your best bet. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - You possess a mind not merely twisted, but actually sprained. - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx/message/ZEC3B6MMXMKLAARBPZ54KYPSHDEL4IAA/
