Comment 39 for bug 88899

I confirm this bug in Jaunty 9.04. I had the same with Hardy 8.04 but the problem was less frequent. I have a latitude d830 since march 2008. That time, I used a debian and all was ok. I installed 8.04 after some months and all was ok. Every while and then, I upgraded the bios up to release A14 and I suspect that the upgrade could be the cause. The processors not only get locked to 800mhz but the scaling is so strong that the system is pretty unusable. When the problem arises, it vanishes after some time (minutes, usually less than 1 hour). The problem seems related to the temperature. I tried even kernel 2.6.30.rc4 with the same results, with/without the nvidia driver.

Thanks for the help,
AC
