[Kernel-packages] [Bug 1512815] Re: read() from pty doesn't finish.
We tested linux-image-3.13.0-67-generic_3.13.0-67.110hf85627v20151105b2_amd64.deb and linux-image-extra-3.13.0-67-generic_3.13.0-67.110hf85627v20151105b2_amd64.deb on Ubuntu 14.04 LTS by running our test program. 3.13.0-45.74 kernel: The problem occurred 2 times at 3300 running. 3.13.0-67.110hf85627v20151105b2 kernel: 0 time at 30 running. We think the fixed kernel works fine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1512815 Title: read() from pty doesn't finish.

[Kernel-packages] [Bug 1253155] Re: Failure to validate module signature at boot time
I'm so sorry. This operation is my mistake. Status Fix Commited is right. But I can't rollback status.
