I remember to have answered to Ingo and he gave me a long lecture (thank him for it, I am a newbee) how to use quilt (because I had updated the patch by hand). In any case, the final version is: http://lkml.org/lkml/2007/11/20/343 It applies to 2.6.25.4 with the following warnings: patching file arch/x86/lib/delay_32.c Hunk #1 succeeded at 40 (offset 2 lines). patching file arch/x86/lib/delay_64.c Hunk #1 succeeded at 28 (offset 2 lines). If you find the patch usefull I will rebase it to 2.6.26-rc3. > > > hi Marin, > > > > here's the patch we are carrying in x86.git at the moment - could you > > please update it with v3 of your code, and send us the patch (with the > > patch metadata kept intact, like you see it below)?

Ingo As far as the patch (in the Ingo's mail) was really the latest, I decided all is OK. But it did not appeared in 2.6.24. That is the story as I know of it ;-) Best regards. Marin Mitov
