[Touch-packages] [Bug 1561973] Re: initramfs upgrade slows system severely
I will be installing Ubuntu 16.04 this month and thus lose the ability to analyze this bug as 14.04 will be overwritten. Can we address this bug now, please, for the benefit of the 14.04 community? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1561973 Title: initramfs upgrade slows system severely Status in initramfs-tools package in Ubuntu: New Bug description: This morning, synaptic offered 2 candidates after clicking on Mark All Upgrades.

[Touch-packages] [Bug 1561973] Re: initramfs upgrade slows system severely
I completely removed gnome-system-monitor and reinstalled. It made no difference. I repeatedly clicked on Refresh in the Processes tab of System Monitor. Some suspiciously large CPU usage values were seen for gnome-system- monitor like 25% (see attached) while the system was idle. ** Attachment added: "Screenshot from 2016-03-25 12:07:32.png" https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1561973/+attachment/4611389/+files/Screenshot%20from%202016-03-25%2012%3A07%3A32.png -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1561973 Title: initramfs upgrade slows system severely Status in initramfs-tools package in Ubuntu: New Bug description: This morning, synaptic offered 2 candidates after clicking on Mark All Upgrades.

[Touch-packages] [Bug 1561973] Re: initramfs upgrade slows system severely
The guest user account is ok. The admin user account is ok. The only account with this problem is the regular user account where all the web browsing occurs. In System Monitor, if I click on either of the Processes or File Systems tabs and stay there for 15 seconds or more, then click back on the Resources tab, I get a low resource history for the past 15 seconds (see attached). It is as if the Resources tab of System Monitor itself is somehow responsible for the excessive CPU usage. ** Attachment added: "Screenshot from 2016-03-25 11:21:15.png" https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1561973/+attachment/4611335/+files/Screenshot%20from%202016-03-25%2011%3A21%3A15.png -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1561973 Title: initramfs upgrade slows system severely Status in initramfs-tools package in Ubuntu: New Bug description: This morning, synaptic offered 2 candidates after clicking on Mark All Upgrades.
