Subject: 3.2-rc2 freezes on boot for AMD K6 - bisected to commit bcb80e53877c2045d9e52f4a71372c3fe6501f6f
Date: Tue, 29 Nov 2011 22:54:39 -0600	[thread overview]
Message-ID: <4ED5B70F.606@lwfinger.net> (raw)

I have an ancient laptop with an AMD-K6 CPU that freezes on boot with 3.2-rc2. 
The problem was bisected to commit bcb80e53877c2.

The cpuinfo for this box is:

 >> cpu.1: cpuinfo
----- /proc/cpuinfo -----
   processor     : 0
   vendor_id     : AuthenticAMD
   cpu family    : 5
   model         : 8
   model name    : AMD-K6(tm) 3D processor
   stepping      : 12
   cpu MHz               : 428.804
   cache size    : 64 KB
   fdiv_bug      : no
   hlt_bug               : no
   f00f_bug      : no
   coma_bug      : no
   fpu           : yes
   fpu_exception : yes
   cpuid level   : 1
   wp            : yes
   flags         : fpu vme de pse tsc msr cx8 pge mmx syscall 3dnow k6_mtrr up
   bogomips      : 857.60
   clflush size  : 32
   cache_alignment       : 32
   address sizes : 32 bits physical, 32 bits virtual
   power management:

----- /proc/cpuinfo end -----

This patch is quite simple, thus it appears that rdmsr() is OK, but that 
rdmsr_safe() is not.

I am happy to provide any other info regarding this box.

Larry
