http://bugzilla.novell.com/show_bug.cgi?id=1023755 Bug ID: 1023755 Summary: Crashkernel fails to reserve memory on DELL 5510 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: richard.palethorpe@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 712998 --> http://bugzilla.novell.com/attachment.cgi?id=712998&action=edit dmesg -H | head -n 1000 My DELL Precision 5510 occasionally freezes, so I want to take crash dumps. However it refuses to reserve the memory for it. I have 32GB of RAM and have tried various values such as crashkernel=128M =512M =512M,high =512M@64M =512M@2048M =256M =256M@30000M etc. Error messages vary, but with 256MB,high: Cannot reserve 256MB crashkernel low memory, please try smaller size "Memory: 2849516K/33396668K available (7308K kernel code, 1267K rwdata, 5100K rodata, 1772K init, 1468K bss, 697720K reserved, 0K cma-reserved)" If it is simply set to 512MB or 256MB or 128M, it says no suitable memory could be found. Setting it with a low offset like 128M@64M results in a message saying the memory is already reserved. I have a number of large tempfs drives on my system which over commit the RAM, but I assume these are mounted much later in the boot process and don't reserve any memory. I have tried using the default SUSE kernel and vanilla 4.10 RC3. iomem: 00000000-00000fff : reserved 00001000-00057fff : System RAM 00058000-00058fff : reserved 00059000-0005efff : System RAM
