cluster reboots sometimes hang (3)

Description

Sometimes, when a cluster machine decides that it wants to reboot as a user is logging out, it ends up hung at the purple ubuntu splash.
Sometimes, sysrq-b will bring the machine back up; sometimes a power-cycle is needed. In the latter case, there is sometimes slight corruption in video memory.
This is more solidly attributable to kexec than #1052 and #1053, and Jon has proposed disabling kexec in r25385

Change History

Encountered this in the field today and it's _definitely_ kexec's fault. I propose we build the change I committed and push it out, and see if that effects the incidence of #1052 and #1053 as well.

  • Status changed from committed to closed
  • Resolution set to fixed

OK, I'm closing this one as fixed, because I think it actually is. There are still underlying issues here in 1052 and 1053
