[LU-1120] Kernel update [RHEL6.2 2.6.32-220.4.2.el6]

• Type: Improvement
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.2.0
• Affects Version/s: Lustre 2.2.0
• Assignee: Yang Sheng
• Reporter: Yang Sheng

Description

This update fixes the following bug:

• An insufficiently designed calculation in the CPU accelerator in the previous
  kernel caused an arithmetic overflow in the sched_clock() function when system
  uptime exceeded 208.5 days. This overflow led to a kernel panic on the systems
  using the Time Stamp Counter (TSC) or Virtual Machine Interface (VMI) clock
  source. This update corrects the aforementioned calculation so that this
  arithmetic overflow and kernel panic can no longer occur under these
  circumstances. (BZ#781974)
