Description Kam Leo 2006-09-15 17:46:00 UTC

Kernel crashes on system with AMD K6-2 450MHz CPU, 256MB RAM. Error occurs after freeing unused kernel memory.  Here is a snippet, hand-typed, from screen. (Sorry, could not save screen dump.)

  Freeing unused kernel memory: 196k freed
  invalid opcode: 0000 [#1]
  SMP
  last sysfile:
  Modules linked in:
  CPU:    0
  EIP:    0060:[<c0103cda>]  Not tainted VLI
  EFLAGS: 00010006  (2.6.18-rc5-git-2-default #1)
  EIP is at check_userspace+0x13/0x19

  Process init (pid: 1, ti=cf790000 task=cf78f5f0 task.ti=cf790000)

Kernel crashes in all modes of install, i.e.
  Installation
  Installation - ACPI Disabled
  Installation - Local APIC Disabled
  Installation - Safe Settings
  Rescue System

This problem also occurs using the Alpha 3 rescue CD.

This appears to be a duplicate of bug #202079 -- albeit using the mini-iso instead of the install iso's -- but I like the title better, and #202079 does not appear to be getting any closer to being solved :-)  Does Novell intend to drop support of legacy cpu's?  I would like to know as soon as possible so I can plan what to do about these machines.  (I found the SMP Kernel only change to be somewhat ominous myself.)  If OpenSUSE needs help fixing this bug, a pointer to detailed directions on how to help debug such a problem would be useful.  (I am not helpless when it comes to debugging Kernel problems, but details of how the installation iso's are compiled and created are not obvious to me just by looking at the factory source directory.)
