Gentlemen, In dumping very large memories we are running up against the 896MB limit in SLES11SP2 (3.0.38 kernel). arch/x86/kernel/setup.c /* * Keep the crash kernel below this limit. On 32 bits earlier kernels * would limit the kernel to the low 512 MiB due to mapping restrictions. * On 64 bits, kexec-tools currently limits us to 896 MiB; increase this * limit once kexec-tools are fixed. */ #ifdef CONFIG_X86_32 # define CRASH_KERNEL_ADDR_MAX (512 << 20) #else # define CRASH_KERNEL_ADDR_MAX (896 << 20) #endif /sbin/kexec we are using is from kexec-tools-2.0.0-53.43.10 Can you tell me if this is limit is removed in the current kexec-tools? And if so, can I use a later release of kexec-tools with this kernel? Or, perhaps you can point me to a patch that removes this limit. Thanks. -Cliff
