Most recent kernel where this bug did not occur:2.6.21
Distribution:gentoo
Hardware Environment:HP nx6125 BIOS version F.11
Software Environment:Gnome 2.18, ati-driver 8.40.4

Looks like the binary ATI driver is used.

Problem Description:If you enable "support for frame buffer devices", "Vesa vga
graphics support" and "ati radeon display support" under "graphics support" so
you lost fan cantrol on your hp nx6125, that means the fan doens't stop
working.

Steps to reproduce:Enable "support for frame buffer devices", "Vesa vga
graphics support" and "ati radeon display support" under "graphics support" on
your hp nx6125 and after the next boot the fan will not switched off.

Does anyone know whether this is likely to be a radeon driver bug or an
acpi bug or something else??

It looks like a thermal issue to me, so I'd say ACPI or the ATI driver (or the
combination of the two).
