https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215590 Bug ID: 215590 Summary: kernel panic trying to restart DVD playback on wakeup from suspend Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: kumba@gentoo.org CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 178301 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D178301&action= =3Dedit Custom kernel config for FreeBSD 11.0-RELEASE-p6 Hi again! I found another kernel panic situation when playing DVD's, kinda similar to the one I detailed in #214705. This one is more subtle, however= , as it appears to be triggered by something in the amd64 trampoline code when attempting to restart DVD playback after resuming from a suspend that was d= one while the DVD was playing. The issue is triggered on a custom kernel that is basically just GENERIC with some unneeded devices/options removed to cut the kernel image's size down. I'll attach my config to this bug. Panic message: Fatal trap 12: page fault while in kernel mode cpuid =3D 1; apic id =3D 01 fault virtual address =3D 0x8 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff802ae88f stack pointer =3D 0x28:0xfffffe01d99b8910 frame pointer =3D 0x28:0xfffffe01d99b8920 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 12 (irq259: ahci0:ch1) trap number =3D 12 panic: page fault cpuid =3D 1 KDB: stack backtrace: #0 0xffffffff806e4b07 at kdb_backtrace+0x67 #1 0xffffffff80699e72 at vpanic+0x182 #2 0xffffffff80699ce3 at panic+0x43 #3 0xffffffff80a1c711 at trap_fatal+0x351 #4 0xffffffff80a1c903 at trap_pfault+0x1e3 #5 0xffffffff80a1beac at trap+0x26c #6 0xffffffff80a00c61 at calltrap+0x8 #7 0xffffffff802ac92c at camperiphdone+0x1bc #8 0xffffffff802b46f7 at xpt_done_process+0x807 #9 0xffffffff802b3edf at xpt_done_direct+0x3f #10 0xffffffff80361dc5 at ahci_ch_intr_direct+0x155 #11 0xffffffff8036082d at ahci_intr_one+0x2d #12 0xffffffff80653e9f at intr_event_execute_handlers+0x20f #13 0xffffffff80654106 at ithread_loop+0xc6 #14 0xffffffff80650ae5 at fork_exit+0x85 #15 0xffffffff80a0119e at fork_trampoline+0xe Uptime: 2h10m43s Dumping 573 out of 7757 MB:..3%..12%..23%..31%..42%..51%..62%..73%..81%..93% KGDB backtrace: Reading symbols from /boot/kernel.custom/zfs.ko...done.

() Current language: auto; currently minimal (kgdb)=20 Steps to reproduce: 1. Insert DVD. 2. Unmount auto-mounted instance from /media. 3. Launch VLC and "Play Disc". 4. Start playing the disc. 5. Puse playback and close the lid on the laptop to put it into suspend. 6. Wait a few seconds until it is fully in suspend, then open the laptop li= d. 7. Wait for the auto-mounter to re-mount the DVD (icon appears on the deskt= op). 8. Restart playback in VLC while the DVD is auto-mounted to /media. 9. Bada-boom! I have not tried this on a GENERIC kernel yet, as part of the reproduction steps requires playing the DVD while it is auto-mounted to /media, and this might trip up the bug described in #214705, as I haven't seen an updated GENERIC kernel come down the pipe yet that contains the fix for that. My custom kernel patches that issue locally for now. The hardware in question is an HP 2000-2b19wm notebook. I can provide additional information if needed to troubleshoot this issue. dmesg: # dmesg Copyright (c) 1992-2016 The FreeBSD Project.
