Summary: Change compile-time option CONFIG_APM_RTS_IS_GMT to
sysctl-tunable kernel parameter
Kernel Version: 2.5.64-mm6 (and others)
Status: NEW
Severity: low
Owner: apmbugs@rothwell.emu.id.au
Submitter: om@iki.fi
Distribution: RH8.0
Hardware Environment: Dell Latitude C600 laptop + docking station
Problem Description:
The fact that CONFIG_APM_RTS_IS_GMT is a kernel compile-time flag instead of a
sysctl-tunable parameter (and companies like RedHat deliver kernels compiled
with this flag on) means that you have to recompile the kernel just to be able
to run Linux in environments where the RTC _cannot_ be set to GMT (like when
co-existing with Windows operating systems). Once set up, the kernel parameter
could be set according to /etc/sysconfig/clock setting at boot time, simplifying
life for all. A quick browse of the apm.c source code makes me think this change
would not really require major work, but of course I could be mistaken.
Steps to reproduce:
The usual problems occur when the kernel compile flag setting does not match
with the actual RTC setting, like time zone changes when switching displays via
the APM BIOS.
