I managed to identify the problem as hardware, as it coincides with physical stresses on the laptop. When I plugged in external peripherals and left the laptop itself alone, the problem did not reoccur. You can close this bug. -- You received this bug notification because you are a member of

2016-01-06 Thread Nick Moffitt
This problem has caused more serious damage recently. When nbd dies and printk()s like mad, the serial console is not fast enough to display it. The kernel keeps allocating buffer space for serial output, which we see as 13G kmalloc-256 or kmalloc-512 kernel threads. Eventually the OOMkiller

Public bug reported: While working on deploying arm64 builders in openstack, we found that it was pretty easy to wedge them. Many hang just running ntpdate right off the bat. William Grant had more direct tests he did, but upgrading from 3.13 to 3.19 didn't seem to fix things. ** Affects:
