The multiple power indicator blink is an intentional time it takes for the internal microSD or eMMC to reach a shutdown voltage. It is not done on XO-1. However, on the XO 1.0 when doing a shut-down, the power light blinks before turning completely off, but when doing a Linux restart, the power light does not blink at any point in the restart process.

Re: Impossible to set date in 11.3.0?
It seems like all that is necessary is to add a test for a secured laptop to allow this patch to go upstream, right?

Announcing Q3C09 for XO-1.5
http://wiki.laptop.org/go/OLPC_Firmware_q3c09 This release fixes a boot hang or fs-update failure if the microSD card is missing, an antenna test that can now test individual antennas, support for ISO 9660 images on USB storage, support for the new fs-load command previously released with Q4D21, and support for fs-update file size checks if olpc-os-builder is also suitably patched. Test reports are encouraged, especially of the antenna test. See http://wiki.laptop.org/go/Antenna_testing for details of that feature. This release is targeted for 12.2.0 inclusion. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I believe you have something here. Something is wrong with the Linux reboots. Perhaps it isnt shutting down 'deep enough' before starting up again anymore. I have a theory that some of the other discussions about date saving and the hwclock behaviour might also be related to what is happening on a Linux reboot. I cannot get the date change to persist to the hw clock on these XO 1.0s without explicitly issuing the hwclock command before then doing an explicit shutdown on these machines. A reboot doesnt work.I will increase the testing of this to other builds and architectures on the other 'date' thread. When you say cold start, do you mean removal of main battery and external power, or do you mean pressing the power button when the power LED is off? Either. I only ever see this spurious lid message when booting into firmware fimmediately upon doing a restart or reboot from Linux on an XO-1 with 12.1.0 and Q2F12. Happens every time on every XO 1.

It occurs whether doing a restart from the GUI on Linux or entering reboot from terminal. Not interesting, but thanks. Neither the speakers nor the battery LED have any direct connection to the lid switch. Again, not doing any lid-switch testing at all, just mentioning any differences when rebooting into firmware from a linux reboot/restart. This is one other thing that is 'different' from a cold restart or a reboot command from firmware. If it does, please get to the ok prompt, type lid-off and press enter (to stop the timer), then test the lid switch like this: ok lid? . cr d# 500 ms many After rebooting from Linux seeing the symptom and entering lid-off after entering the above command, saw fff fff fff fff . .

It used to do that on shutdown as part of /etc/rc.d/init.d/halt and friends, but I think it got dropped as part of the switch to systemd. grep hwclock /etc -r doesn't find anything.

12.1.0 release candidate 8 (build 21) released
Hi, We're pleased to announce the next release candidate of our new 12.1.0 software release. Information and installation instructions can be found here: http://wiki.laptop.org/go/Release_notes/12.1.0 Quick links for those who know which files need to be grabbed and save to USB disks: http://download.laptop.org/xo-1.75/os/candidate/12.1.0-21/ http://download.laptop.org/xo-1.5/os/candidate/12.1.0-21/ http://download.laptop.org/xo-1/os/candidate/12.1.0-21/ This is a signed release candidate that can be installed on all XOs, even those with security enabled. We're looking for testing and feedback on all aspects of the system. Thanks for any help you can offer, and for all the feedback that was received throughout development. This is expected to be the final release candidate before official release. Please review the Known problems section of the release notes. Some documented issues are carried over from previous releases, but others are new and are things that we will aim to fix in the time remaining before release. Compared to 12.1.0 release candidate 7 (build 20), we have fixed: The XO-1.5 was hanging when suspending while networking was disabled (#12043) Browse was crashing after logging into the school server moodle page for the first time (SL#3825) Some javascript-related Browse crashiness was fixed on XO-1.75 (SL#3776) Thanks! ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
