https://bugzilla.kernel.org/show_bug.cgi?id=211467 --- Comment #1 from jonny5532 (jonny@xxxxxxxxxxxxxxxxx) --- Created attachment 294993 --> https://bugzilla.kernel.org/attachment.cgi?id=294993&action=edit Simple patch which appears to fix it This patch stops my VM crashing without removing the truncation. It is based on the assumption that a SYSENTER which changes the CS flags to long mode (if applicable) should also change the ctxt->mode to PROT64. I don't know if that is correct (or safe) though. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
