Hi all,

I am running qemu on an x86 host and when the host reloaded we do see a core on Qemu and the gdb dump shows as follows.

Can any one please let me know if any one has come across such failures.

rning: Can't read pathname for load map: Input/output error.

Core was generated by `/usr/bin/qemu-system-x86_64 -name default-sdr--2 -S -M pc_q35 -enable-kvm -m 61'.

Program terminated with signal 11, Segmentation fault.

Not a kernel bug, and the bug was also reported (and closed) on the QEMU bug tracker.
