The QEMU dum= ps suggest a problem handling a page fault and the original report implicates = the new huge_fault handler. So let's log anything from the huge_fault handler = that doesn't install the pte. Please apply this patch to your stock v6.14.4 ker= nel and report the resulting dmesg after the VM crash. --=20 You may reply to this email to add a comment.
