I am trying to debug the tmpfs module. =20 Panic message on console is: =20 Fatal double fault rip =3D 0xffffffff80552be1 rsp =3D 0xffffffff006f5000 rbp =3D 0xffffffff006f5000 cpuid =3D 0; apic id =3D 00 panic: double fault cpuid =3D 0 Uptime: 1h16m8s Physical memory: 4555 MB Dumping 207 MB: 192 176 160 144 128 112 96 80 64 48 32 16 Dump complete =20 =20 I tried searching this problem on google also but with no help. =20 Any help will be appreciated. =20 Thanks, Mayank =20 =20 =20 =20
