[Bug 518567] Re: armel/versatile: Can't kexec
Tried again with the kernel at http://people.canonical.com/~roc/kernel/kexec/ prepared by Bryan from the sources at http://kernel.ubuntu.com/git?p=roc/ubuntu- lucid.git;a=shortlog;h=refs/heads/kexec-versatile: qemu-system-arm -m 256 -drive file=lucid.img,media=disk -M versatilepb -cpu cortex-a8 -kernel linux- image-2.6.32-16-versatile_2.6.32-16.24/boot/vmlinuz-2.6.32-16-versatile -append 'root=/dev/sda console=ttyAMA0,115200 S' -nographic kexec -l vmlinuz-2.6.32-16-versatile --append=rootwait root=/dev/sda console=ttyAMA0,115200 S kexec -e All I get is: [ 87.854989] Starting new kernel But at least it doesn't dump core anymore; apparently it avoids writing bogus data over the I/O space. I also tried without rootwait, but I really get no more output after Starting new kernel despite the use of a serial console. -- armel/versatile: Can't kexec https://bugs.launchpad.net/bugs/518567 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
[Bug 518567] Re: armel/versatile: Can't kexec
So booting the same kernel and kexec-loading a vmlinux instead (created from the vmlinuz bzImage) works! I can't boot the vmlinux in qemu though. -- armel/versatile: Can't kexec https://bugs.launchpad.net/bugs/518567 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
[Bug 518567] Re: armel/versatile: Can't kexec
What I meant in comment #2 was that I can't use qemu-system-arm -kernel vmlinux ..., this hangs (without even initializing the fb); if I boot qemu-system-arm with a vmlinuz and kexec the vmlinux, it works. Summary: qemu-system-arm: works with vmlinuz, not vmlinux kexec: works with vmlinux, not vmlinuz -- armel/versatile: Can't kexec https://bugs.launchpad.net/bugs/518567 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

Closing the linux task since it works with the in archive kernel just fine (didn't actually test initramfs though). ** Changed in: linux (Ubuntu) Status: New = Invalid -- armel/versatile: Can't kexec https://bugs.launchpad.net/bugs/518567 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
[Bug 518567] Re: armel/versatile: Can't kexec
So what remains to be fixed here is kexec on qemu/versatile when an using a vmlinuz; either it should properly compute the address (not sure what actually breaks when using a vmlinuz) or it should unconditionally unpack the vmlinuz into a vmlinux (to save time when kexec -e comes). -- armel/versatile: Can't kexec https://bugs.launchpad.net/bugs/518567 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
