The hardware is a slimline PC sold here as Acer L5100. I think it contains a bunch of components normally used in laptops and according to the lspci output (see attachments above) it uses some AMD/ATI "IO"-chipset(s).
As everything works fine with a amd64/x86_64 kernel I do not like the idea of messing around with BIOS settings (I haven't seen any obvious settings related to the CPU problem). I found a german ubuntu forum meanwhile where someone documented the same problem with the same hardware. [ I also compiled 2.6.25 myself to check the new kernel but I failed to repackage a working initrd based on the 2.6.24 initrd of ubuntu ... So I'm eagerly waiting for Fedora 9 with 2.6.25 kernel for further tests ... ] Erik -- Athlon X2 Dual Core Processor - Second CPU/Core not working with i386 kernel https://bugs.launchpad.net/bugs/213011 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
