https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230993 Bug ID: 230993 Summary: sysutils/acpi_call: Kernel panic since CURRENT r336876 (Use SMAP on amd64) Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: theron.tarigo@gmail.com CC: gelraen.ua@gmail.com Flags: maintainer-feedback?(gelraen.ua@gmail.com) CC: gelraen.ua@gmail.com Attachment #196667 text/plain mime type: Created attachment 196667 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D196667&action= =3Dedit Fix Using acpi_call on CURRENT since r336876 causes a kernel panic on some hardware. Investigating the problem reveals an attempt to use a userspace pointer from within the kernel module (passed to the acpi_call_fixup_pointe= rs routine). This evidently is no longer allowed under use of Supervisor Mode Access Protection. --=20 You are receiving this mail because: You are the assignee for the bug.=
