Hi, Firmware upgrade doesn't help always, like not in my case. I have upgraded to the latest bios version A3 on latitude D420 and can confirm that the problem hasn't disappeared by BIOS upgrade. It doesn't happen very often in my use, but it has happened once, therefore the problem remains.

[Bug 43745] Re: Ubuntu corrupts real time clock on some dell laptops
I have a Dell Inspiron 6400, running Edgy with some packages from Feisty, in particular kernel 2.6.20-9-lowlatency, version 2.6.20-9.16. I frequently put the laptop in suspend-to-disk using `hibernate`. After a number of hibernate-wakeup cycles, it starts going downhill. First, the Grub timer doesn't count down. But I can hit Esc and then select the kernel manually, then the system boots and restores my desktop OK. The desktop clock is still showing the time when the system was put to hibernation, but after about 1 minute, it gets synchronised to the correct time (ntp kicking in?). Now, after I hibernate the system once more and wake it up again, the clock doesn't get updated to the correct time. It's still running however, but it's behind. If the system stayed in hibernate for 1 hour, the clock will be 1 hour behind. Doing sudo hwclock --hctosys results in this: select() to /dev/rtc to wait for clock tick timed out I didn't dare to force a full power-on test, because I've heard some people had to change their motherboards after that.

It is with great sadness that I report Kubuntu 6.10 Edgy corrupts the bios on my old (5 years) Inspiron 8000 Pentium 3 1GHZ. So it appears that this problem is not limited to newer hardware. Installed Kubuntu 6.10 Edgy, rebooted 5 times or so. And when booting up the Bios message appeared stating that the date/time had been lost and did I want to F1 Set the date/time now or F2 ignore this error. Luckily this BIOS has more user friendly options than my Inspiron 6400 which simply displays the infuriating time of date clock stopped message and then fails to boot or do anything.

Hello I've searched the web for this problem and here is an idea I found. It makes sense so I'm thinking it might be the answer to what causes the bug. This is why I post it here so that Ben Collins can check it out: Just on of those late night thoughts as I reread some of this. What if the problem is that Linux somehow uses access to the CMOS in a way that tends to draw down the battery? That would make having a new, fresh battery (well connected) a critical item, and would explain why some posters (your name) have problems that come back after a few days (battery more used or in a colder enviornment??) and why there are so many 6400s out there with no such problem and why those with the problem seem to be unable to predict when it will happen or not. Also, has anyone tried the rtc-resume.c? Good luck solving the bug. As soon as it's fixed I might reconsider and buy a Dell laptop.

access to the CMOS in a way that tends to draw down the battery? This sounds wrong. Whenever I had this problem with the CMOS clock I just removed the CMOS battery for about 30 seconds and reinserted the same battery and everything was working again. So the battery was not empty and I never replaced it with a new battery. I'm still pretty sure the kernel just sometimes corrupts somehow something in the BIOS (A very exact explanation, isn't it? ;-). Removing and re-inserting the battery just causes the BIOS to reset properly so everything works again. And it must be the kernel which corrupts the BIOS and no other appliations because I can reproduce the problem by just starting the kernel again and again with the option init=/sbin/reboot. So in my opinion fiddling around with the /etc/init.d/hwclock stuff is not a solution. -- Ubuntu corrupts real time clock on some dell laptops https://launchpad.net/bugs/43745 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 43745] Re: Ubuntu corrupts real time clock on some dell laptops
Hi, first of all sorry for my bad english!! When I'was booting my Dapper 6.06 on my Dell Optiplex SX280 for the first time, i got the well known select() to /dev/rtc to wait for clock tick timed out problem. I decided to upgrade the SX280 BIOS from rev. A04 to A08 before trying anything else. ¡And it worked fine! Now my Dapper boots with no problem. -- Ubuntu corrupts real time clock on some dell laptops https://launchpad.net/bugs/43745 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello again, I forgot, I'm upgraded to bios revision A08 last week.

[Bug 43745] Re: Ubuntu corrupts real time clock on some dell laptops
As a continuation to my previous post (see above). After removing and replacing the coin cell battery, the laptop started booting again. (not that I did like to this again, as I had to remove the keyboard). Also, Grub is once again able to count down and boot automatically. [...] FYI: Turns out that Dell has a BIOS diagnostics tool for download (works as a bootable ISO). I would like to suggest to folks with this problem, that are still able to boot, to try using it; in order to help diagnose this.
