AFAICT this is related to bug kern/155585. I see that bug is closed, because it was "merged to stable/9". Obviously it is not merged into 8.4; is it in 9.1? 9.2? bye & Thanks av. > The following information is contained in the encrypted panic > report at the end of this email: > >> Dump header from device /dev/mfid0s1b >> Architecture: amd64 >> Architecture Version: 2 >> Dump Length: 1188327424B (1133 MB) >> Blocksize: 512 >> Dumptime: Thu Apr 17 13:20:27 2014 >> Hostname: xxxxx.xxxxxxxx.xx >> Magic: FreeBSD Kernel Dump >> Version String: FreeBSD 8.4-RELEASE-p8 #7 r264450: Mon Apr 14 10:35:51 CEST 2014 >> root@xxxxx.xxxxxxxx.xx:/usr/obj/usr/src/sys/XXXXX >> Panic String: double fault >> Dump Parity: 2547754091 >> Bounds: 17 >> Dump Status: good >> >> Backtrace: >> Reading symbols from /boot/kernel/splash_bmp.ko...Reading symbols from /boot/kernel/splash_bmp.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/splash_bmp.ko >> Reading symbols from /boot/kernel/linprocfs.ko...Reading symbols from /boot/kernel/linprocfs.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/linprocfs.ko >> Reading symbols from /boot/kernel/linux.ko...Reading symbols from /boot/kernel/linux.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/linux.ko >> Reading symbols from /boot/kernel/nullfs.ko...Reading symbols from /boot/kernel/nullfs.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/nullfs.ko >> Reading symbols from /boot/kernel/fdescfs.ko...Reading symbols from /boot/kernel/fdescfs.ko.symbols...done. >> done. >> Loaded symbols for /boot/kernel/fdescfs.ko >> #0 doadump () at pcpu.h:224 >> in pcpu.h >> (kgdb) #0 doadump () at pcpu.h:224 >> #1 0xffffffff803104f8 in boot (howto=260) >> at /usr/src/sys/kern/kern_shutdown.c:443 >> #2 0xffffffff803109e7 in panic (fmt=0x1
