High cpu usge and high io percentage
by JD 25 Nov '16

25 Nov '16

ext4-rsv-conver ?? In kernel source ..../fs/ext4/super.c we see /* * The maximum number of concurrent works can be high and * concurrency isn't really necessary. Limit it to 1. */ EXT4_SB(sb)->rsv_conversion_wq = alloc_workqueue("ext4-rsv-conversion", WQ_MEM_RECLAIM | WQ_UNBOUND, 1); if (!EXT4_SB(sb)->rsv_conversion_wq) { printk(KERN_ERR "EXT4-fs: failed to create workqueue\n"); ret = -ENOMEM; goto failed_mount4; } However, there is no other reference to this symbol in the rest of the kernel source. Reason I am asking is that it is often shown using much cpu bandwidth, and much io percentage (/bin/iotop -d 3).

F25-Atomic - Error creating Vagrant synced folder
by Juan Orti Alcaine 25 Nov '16

25 Nov '16

Hi, I'm launching a fedora/25-atomic-host with Vagrant but it fails to create the synced folder although the VM boots fine and I can ssh in it. I haven't done any customization, just launching the box like explained in the instructions to get Fedora 25 Atomic. Should I open a bug? This is the error: --- The following SSH command responded with a non-zero exit status. Vagrant assumes that this means the command failed! mkdir -p /vagrant Stdout from the command: Stderr from the command: mkdir: cannot create directory ‘/vagrant’: Operation not permitted --- Thanks. -- Juan Orti https://apuntesderootblog.wordpress.com/ GPG: 61F0 8272 6882 BCA6 3A35 88F6 B630 4B72 DEEB D08B

F25: XFCE won't start
by Marco Guazzone 25 Nov '16

25 Nov '16

Hello, I've installed F25 Workstation x64 from Live iso (GNOME window manager). Now I want to run XFCE window manager. I installed it with: dnf groupinstall Xfce Then rebooted and tried to log in (by selecting XFCE from GDM). But after clicking on the log in button, XFCE seems to have problems and the screen immediately comes back to the GDM login. Any idea? Thanks. Best, -- Marco

Umatrix Firefox Addon -
by Bob Goodwin 25 Nov '16

25 Nov '16

Does anyone know why Firefox no longer allows the umatrix addon, not since the update to Firefox 50 two days ago. Umatrix was removed and would not install. I had to downgrade to Firefox 49 and install a copy from the umatrix web page to get it back again.

Epson XP-332
by DB 24 Nov '16

24 Nov '16

Good evening all! I've recently bought an Epson all-in-one & am having a pile of difficulty to get it to work properly. a) Connected via USB, it appears to work. b) Connected via wifi, it'll print but not scan. c) operating via Oracle VirtualBox it does not get recognised, Does anyone have any ideas how one may get the scanner to operate via wifi?? Does anyone know how to get the colour corrected after scanning?? Many thanks for any suggestions Dave Fedora 24 4.7.9-200.fc24.x86_64

VlC and latest kernel/nvidia update error
by fedora2015 24 Nov '16

24 Nov '16

I am getting this error message on two PC's: Error: Transaction check error: file /etc/ld.so.conf.d/nvidia-lib64.conf from install of nvidia-driver-cuda-libs-2:375.20-1.fc24.x86_64 conflicts with file from package xorg-x11-drv-nvidia-340xx-libs-1:340.96-2.fc24.x86_64 This occurs with latest kernel and nvidia update. Only way to complete the nvidia update is to remove VLC. Since I'm not an expert, should I file a bug report?

"Solar" plymouth theme is broken in 25, should not be enabled
by Sam Varshavchik 24 Nov '16

24 Nov '16

One of my usual post-Fedora upgrade rituals is to reset the default plymouth theme back to solar. There's a long-standing bug with system upgrades always resetting the plymouth theme to the default "charge". That bug is somewhere in Bugzilla, gathering dust. Well, having done this again, I was dismayed to see that the solar theme is completely broken. One of my laptops still boots, but instead of smooth animation, the theme basically suffers from Tourette's syndrome from start to finish, constantly flickering between two frames. Laptop #2 doesn't even boot at all, after switching to the solar theme. That laptop uses LUKS encryption. The solar theme briefly flickers on and off, and that's it. Instead of the password prompt, all I get is a black VGA screen. The LUKS password prompt doesn't appear. I was able to edit the grub boot script, and remove the "rhgb" keyword. This allowed the laptop to boot, at which point I went back the default "charge" theme. Created bug 1398061 for that. Hopefully, it won't end up gathering dust like its predecessor. Laptop #1 also has a weird X problem where the initial login seems to work fine (except for the laptop's fingerprint scanner no longer getting activated, which is a different story), but if I log out, and attempt to log back in a second time, the laptop behaves as if X comes up at first, but then crashes immediately back to VGA mode, then going back into X mode, than crash again, about 3 or 4 times, before X manages to come up into my desktop. Laptop #2 does not exhibit this weirdness. I suspect this has something to do with Wayland (sigh). #1 uses noveau, #2 uses intel. There is a blurb in the release notes about turning off wayland from gdm, but nothing is said about lightdm, which I'm using. Overall, looks like 25 is shaping up to be a rough release.

dnf system-upgrades wants to remove the running kernel
by Andras Simon 24 Nov '16

24 Nov '16

I'm trying to upgrade to F24 from F23. # dnf system-upgrade download --releasever=24 Last metadata expiration check: 0:10:02 ago on Wed Nov 23 18:52:12 2016. Error: cannot install both kernel-PAE-4.5.5-300.fc24.i686 and kernel-PAE-4.7.10-100.fc23.i686 (try to add '--allowerasing' to command line to replace conflicting packages) kernel-PAE-4.7.10-100.fc23.i686 is actually the one that's running (and in fact the only one). With --allowerasing I get [...] Removing: kernel-PAE i686 4.7.10-100.fc23 @updates Allowing dnf to do this seems a bit risky to me. What's the real problem that makes dnf complain? (The error message is not very helpful: dnf shouldn't try to install kernel-PAE-4.7.10-100.fc23.i686, as it is installed already.) And how do I work around it? Thanks, Andras
