Doesn’t work for me on Lucid amd64. I have 2 GiB of memory, and I have crashkernel=384M-2G:64M,2G-:128M in /proc/cmdline, but the kernel detects that I have ever-so-slightly less than 2 GiB of memory, and therefore gives me a 64 MiB crashkernel:
[ 0.000000] Reserving 64MB of memory at 32MB for crashkernel (System RAM: 2046MB) When I trigger a panic, it successfully starts the crashkernel, but then the crashkernel runs out of memory and panics itself. -- linux-crashdump fails to record crash; reports memory not reserved https://bugs.launchpad.net/bugs/321970 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
