Title:
qemu-system-i386 verison 2.5.50 fails at lmsw instruction
Status in QEMU:
Expired
Bug description:
I cloned qemu source code from github.com, and compiled it on my
Kubuntu 15.10 laptop to run my little OS. When booting my little OS,
the virtual machine's screen keep blinking, I guess it's the virtual
machine rebooting on and on automatically for some unknown reason, but
there is no further information shown on Kubuntu's terminal. I'm
pretty sure this problem is not caused by my little OS, because it
works just fine in qemu-system-i386 version 2.5.0.
I debugged my OS and find this problem happens when executing
instruction "lmsw ax". Is this a bug, can anyone help me out?
