Package: linux-image-2.6.18-6-486 Version: 2.6.18.dfsg.1-22etch2 Severity: minor
I think this is minor, but it caught my attention and I thought the package maintainer might want to know about it. Upgrading this package from 2.6.18.dfsg.1-22 to 2.6.18.dfsg.1-22etch2 caused the bogomips benchmark to drop from 99.07 to 20.03 on a Vortex86SX based computer. Downgrading this package back to 2.6.18.dfsg-1-22 (using "apt-get install linux-image-2.6.18-6-486=2.6.18.dfsg.1-22"), and changing nothing else, restored the bogomips rating back to 99.07. I do not know if the computer actually ran slower. I didn't notice a difference while using it, it was just the bogomips number that caught my attention. If additional testing would be helpful, please suggest something that would run on a minimal (command-line only) Etch installation. The computer is an Ebox 2300SX, which is a tiny x86 computer that contains a Vortex86SX processor running at 300MHz. (More CPU info at http://www.dmp.com.tw/tech/vortex86sx/) I installed Debian Etch 4.0.r4 which came with version 2.6.18.dfsg.1-22 of the package linux-image-2.6.18-6-486. During startup, the computer reported 99.07 BogoMIPS which was in line with other reported ratings (i.e. 1/3 the processor clock). After the installation, I added security.debian.org to /etc/apt/sources.list and used apt-get to upgrade the installed packages. According to the time stamps of the installed files and the log files, it was the next reboot that showed the reduced BogoMIPS.
