Hello: On Domingo, 13 de Septiembre de 2009 20:51:40 Ben Hutchings escribió: Piotr, Has this been fixed? Does the current linux-image-2.6.26-2-486 work on this system? (If it crashes in text_poke_early() instead of behaving as before, that is a separate bug that we have a fix for.) Ben. Thanks for caring about this issue. I'm not sure if I have the very same hardware as Piotr, but I think I reproduced the problem with latest lenny kernel. See [0] As I have mentioned in a previous follow-up, the problem is solved removing virtuallization support, see previously posted patch 0.9-lenny.diff When this patch is applied, I get a working kernel. See [1] and mind that kernel panic at the end is caused by a totally different reason. If you think this is a different problem I may arrange further testing with some patches. I've also tried 2.6.30 from backports and it found working as is without needing any further patch.

Hello... I'd like to contribute with my own experiencie with a boot error like the subject: I had a P3 with a Aopen motherboard with 4 kernels: 2.6.25-686 from testing 2.6.26-686 from testing 2.6.25 and 2.6.26 compiled by me with march=pentium3 mtune=pentium3 and using floating point. I got an old DFI motherboard with P4 and I conected the disk from Aopen motherboard, and I could boot using all four kernels. After that I compiled 2.6.26 using march=pentium4 mtune=pentium4 and floating point, it was impossible boot from this kernel, I got the same message of the subject, others boot O.K. After some tries, I got boot from this kernel compiling it without floating point. So : pentium3+floating point - O.K. pentium4+floating point - NO.K.
