Hello ,


I am investigating a issue that our test group reported concerning this dri=
ver.
 Their test loads and unloads every kernel module included in the Oracle
4.14.35 kernel release . You don=E2=80=99t even need a AMD platform . It oc=
curs on any
Intel,  or a  KVM VM instance too.=20

Kernel panic while =E2=80=9C  modprobe amdkfd ;  modprobe -r amdkfd  =E2=80=
=9C

Looks like some memory corruption.=20

Sometimes  the unload works but the message logged is garbage:

[root@jpd-vmbase02 ~]# modprobe -r amdkfd
[  144.449981] ???????????? hn??=E8=9F=9F??xn??=D7=9F??kfd: Removed module


Is  this something one of team members could have possibly corrected in an
upstream version ?

#define KFD_DRIVER_DESC         "Standalone HSA driver for AMD's GPUs&=
quot;
#define KFD_DRIVER_DATE         "20150421"
#define KFD_DRIVER_MAJOR        0
#define KFD_DRIVER_MINOR        7
#define KFD_DRIVER_PATCHLEVEL   2


Thank you,

John
