Most recent kernel where this bug did not occur: 2.6.18.rc4 This regression was introduced at 2.6.18-rc5, 2.6.18-rcn where n = 1,2,3 or 4 are OK. For n = 5,6 or 7, the bug is present. 2.6.17.n are all ok for n up to 13, at least. Distribution: dedian sarge with kernal.org kernel.

Created attachment 9026 [details] configuration 2.6.18-rc4 Configuration 2.6.18-rc4: no problem.
Created attachment 9027 [details] 2.6.18-rc5 configuration 2.6.18-rc5 configuration: has bug.
please attach the output from dmesg -s64000 for both the working -rc4 and the failing -rc5.
Created attachment 9082 [details] dmesg -s 64000 from 2.6.18-rc4 dmesg from good 2.6.18-rc4
Created attachment 9083 [details] dmesg -s64000 from failing 2.6.18-rc5 dmesg from failing 2.6.18-rc5, not very useful, I fear. (Turning on acpi debug seemed to produce no relevant info..)
Created attachment 9084 [details] dmidecode from target machine dmidecode: old bios, quirky partly because of dual boot historical problems. However, this has not changed recently and certainly not between 2.6.18-rc4 and 2.6.18.rc5.
As expected, 2.6.18 suffers from the same bug: no soft power down.
Not suprisingly, 2.6.19-rc1 has the problem.
Resolved: APM rather than ACPI should have been set. Apologies for the noise. Will close bug if I am permitted to do that.
