[Bug 43745] Ubuntu corrupts real time clock on some dell laptops

[mimp]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Major
       Priority: (none set)
         Status: Confirmed


Description:

has more information

After installing dapper several people have reported their computers have failed to boot with the error 'real-time-clock stopped'
The error prevents the computer entering bios setup or booting from a cd so is fairly fatal, it can be resolved by removing the coin-cell battery and replacing it again after several seconds.

There is a postential solution offered which involves editing
/etc/init.d/hwclock.sh but as this happened to me during the install
process itself that's not particularly useful
