[Bug 39499] System doesn't power down under Dapper 686

[Tommy Trussell]

Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-20-686 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I have an eMonster 550r system that I have used with Warty, Breezy and
now Dapper.

Under the Dapper 686 kernel(s) when I shut down the system, it goes
through the normal shutdown sequence, and the hard drive spins down, but
the CPU continues running until I press the power button. Under the 386
kernel the system beeps several times and the power goes off.

[BTW in Dapper I also discovered that pressing the power button in a
running system does not start a shutdown sequence, but just kills the
power. This is true for both the 386 and 686 kernels. The power button
started a shutdown sequence in Breezy.]

Here's what /proc/cpuinfo says:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 7
model name      : Pentium III (Katmai)
stepping        : 3
cpu MHz         : 551.474
cache size      : 512 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2

bogomips        : 1103.71

Forgive my cluelessness but someone may have to lead me through any
additional identifying information needed.
