https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214597 Bug ID: 214597 Summary: [panic] Fatal trap 9 while mounting SD card with lock switch on Product: Base System Version: 11.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: felix.the.red@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 177106 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D177106&action= =3Dedit Screencap of fatal trap 9 While trying to mount an SD card with the lock switch on (very much like PR 94838), I get a kernel panic and fatal trap 9. The difference with this PR = is that they were running on 6.1-PRERELEASE, whereas I am running on 11.0-RELE= ASE (p2), so the condition either wasn't fixed or was reintroduced. I insert the SD card and the console shows: ugen0.7: <Generic> at usbus0 umass1: <Bulk-In, Bulk-Out, Interface> on usbus0 umass1: SCSI over Bulk-Only; quirks =3D 0x4000 umass1:2:1: Attached to scbus2 da1 at umass-sim1 bus 1 scbus2 target 0 lun 0 da1: <Generic- SD/MMC/MS PRO 1.00> Removable Direct Access SPC-2 SCSI device da1: Serial Number 20121112761000000 da1: 40.000MB/s transfers When I try to mount the SD card with mount -t msdosfs /dev/da1s1 /mnt I get: Fatal trap 9: general protection fault while in kernel mode cpuid =3D 1; apic id =3D 01 I'm not going to type out the panic information - I took a photo of it and it's attached to this PR. I can reliably reproduce this by inserting the SD card with the physical=20 write protect set, trying to mount it (which fails), and then either (1) tr= ying to unmount the device or (2) removing the SD card. I'm running on: FreeBSD laptop 11.0-RELEASE-p2 FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24 06:55= :27 UTC 2016 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERI= C=20 amd64 I have the core files, if that helps. I also have a few KLDs loaded: kern.vty=3Dvt fuse_load=3D"YES" vboxdrv_load=3D"YES" atapicam_load=3D"YES" I'm willing to help troubleshoot, just let me know what you need. --=20 You are receiving this mail because: You are the assignee for the bug.=
