boot failure with the same symptoms ('No CPUID...' message in dmesg
followed by an OOPS, non-functional X) on a Thinkpad Edge 13 w/ Intel

Great, that's the correct behavior. Non supported CPU will encounter the NULL pointer dereference OOPS. The patch fixed the problem.

I guess blacklisting the module isn't enough, then?

Well, the kernel 2.6.35-22 booted with no noticeable issues with intel_ips blacklisted. -- Kernel Oops - unable to handle kernel NULL pointer dereference; IP: [a007e3c6] ips_detect_cpu+0x76/0x1d0 [intel_ips] https://bugs.launchpad.net/bugs/648631 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

Also, looking at the edited report, perhaps you didn't read one of my comments closely enough. I don't know whether the kernel 2.6.35-16 works because I never had it installed for some reason. I'd test it, but I did some looking around and I can't seem to find any packages for it. I found the source at https://launchpad.net/ubuntu/+source/linux/2.6.35-16.22 though, should I compile it myself or something? -- Kernel Oops - unable to handle kernel NULL pointer dereference; IP: [a007e3c6] ips_detect_cpu+0x76/0x1d0 [intel_ips] https://bugs.launchpad.net/bugs/648631 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

In that case, it looks like this is probably the change that introduced the bug (from the 2.6.35-17 changelog): * [Config] Enable INTEL_IPS - LP: #601057 Could you compile the current Ubuntu kernel, disabling the INTEL_IPS module and testing that? -- Kernel Oops - unable to handle kernel NULL pointer dereference; IP: [a007e3c6] ips_detect_cpu+0x76/0x1d0 [intel_ips] https://bugs.launchpad.net/bugs/648631 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

Which kernel do you want me to attach the output of? All of the ones I've tested? Two other observations which I probably should've mentioned before, I'm not sure if they're related or not: I also have this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/642421 It doesn't actually seem to do anything to the others with it, but since it's a modprobe error and modprobe seems to be what's crashing.. When I run startx from a terminal on a broken kernel, all I get is a completely black screen. When trying to reboot using the magic sysrq key, after pressing sysrq + e I'm taken to a terminal for a brief moment, after which X suddenly starts up, complaining that it couldn't load the screne properly. -- Kernel Oops - unable to handle kernel NULL pointer dereference; IP: [a007e3c6] ips_detect_cpu+0x76/0x1d0 [intel_ips] https://bugs.launchpad.net/bugs/648631 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
