Esel,

Could you provide me the stack trace you are facing (without
intel_idle.max_cstate=0 in bootparam). Then you should test enabling
intel_idle.max_cstate=0 into bootparams and see if the problems happen.
If you problem is related to intel_idle module, I'd love to use your
case as a "testcase" to fix this.

Do you know how to enable linux-crashdump ? Do you think you could
enabled it and provide me the coredump when you get such error ?

And yes! For your case (Proliant < Gen8) the "workaround" cmdline should
be:

"nox2apic intermap=off intel_idle.max_cstate=0"

Tks!

Title:
  HP Proliant Serverrs - DL360 and DL380 Gen8 - Precise Kernel Panic -
  General Protection Fault and X2APIC/XAPIC boot parameters

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Precise:
  In Progress

Bug description:
  It was brought to my attention the following situation:

  """
  We massively upgraded our Ubuntu 12.04 servers (most of them are HP
  DL360p Gen8 or DL380 Gen8) to 3.2.0-67 kernel And in the last 2-3
  days we already had to reboot 5 of them because they completely hang

  Some of them had the following messages under syslog :
  kernel: [384707.675479] general protection fault: 0000 [#5666] SMP

  others had :
  kernel: [950725.612724] BUG: unable to handle kernel paging request

  All of them have this also :
  your BIOS is broken and requested that x2apic be disabled
