Nothing to do with NFS, I > don't use it. That's useful to know. I've turned off my NFS mounts completely to see what happens but my own reason for suspecting it was the 'D'-state WCHAN value plasmashell gets into. If it's not NFS then it's almost certainly some other kernel bug. This is a situation that should never arise even with a badly-behaved program, but so far I haven't found anything else which triggers it. I find I have to reboot the machine to clear it, which again is typical of this kind of bug. poc _______________________________________________ kde mailing list -- kde@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kde-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/kde@xxxxxxxxxxxxxxxxxxxxxxx
