Forwarding to kexec list. http://lists.infradead.org/mailman/listinfo/kexec ----- Forwarded Message ----- From: "Chandan12 K" <chandan12.k@xxxxxxx> To: Crash-utility at redhat.com Sent: Wednesday, August 12, 2009 2:08:54 AM GMT -05:00 US/Canada Eastern Subject: [Crash-utility] vmcore file size 0 on x86_64 Hi, I am little new in this mailing list. I just wondered if anybody could help me regarding the vmcore file generation. I ran kexec on my x86_64 machine, and the /proc/vmcore file is created with zero size. However, even if I read the /dev/oldmem file, I am only able to read till 16M. I guess I am only able to read till the 'X', where X is crashkernel=Y at X. Moreover, My machine seems to have 32 bit user space and ofcourse, 64 bit kernel space. Appreciate any response.
