I have done some debugging, so i try to tell you what i discovered, hoping
some of you can help me.
I have noticed that after some delay the hdd led was flashing, so i waited
before rebooting.
Doing so, after the hard reboot, i can find some log written.
First, i opened XFree86.0.log and found the following error:
**) R128(0): DPMS enabled
(EE) R128(0): R128CCEWaitForIdle: CCE idle -1007
(EE) R128(0): Idle timed out, resetting engine...
(EE) R128(0): R128CCEWaitForIdle: CCE reset -1007
(EE) R128(0): R128CCEWaitForIdle: CCE start -1007
(EE) R128(0): R128CCEWaitForIdle: CCE idle -1007
(EE) R128(0): Idle timed out, resetting engine...
(EE) R128(0): R128CCEWaitForIdle: CCE reset -1007
(EE) R128(0): R128CCEWaitForIdle: CCE start -1007
(EE) R128(0): R128CCEWaitForIdle: CCE idle -1007
(EE) R128(0): Idle timed out, resetting engine...
( the messages where repeated FOREVER )
And, in kern.log:
Mar 6 19:10:12 shimitar vmunix: [drm:r128_cce_idle] *ERROR* r128_cce_idle
called without lock held
Mar 6 19:10:12 shimitar vmunix: *ERROR* r128_cce_reset called without lock
held
Mar 6 19:10:13 shimitar vmunix: [drm:r128_cce_start] *ERROR* r128_cce_start
called without lock held
Mar 6 19:10:14 shimitar vmunix: [drm:r128_cce_idle] *ERROR* r128_cce_idle
called without lock held
Mar 6 19:10:14 shimitar vmunix: [drm:r128_cce_reset] *ERROR* r128_cce_reset
called without lock held
Mar 6 19:10:16 shimitar vmunix: [drm:r128_cce_start] *ERROR* r128_cce_start
called without lock held
( again, these messages where repeated several times )
So i opened the files (r128_cce.c and r128_state.c mainly) and discovered that
the macro
#define LOCK_TEST_WITH_RETURN( dev ) \
do { \
if ( !_DRM_LOCK_IS_HELD( dev->lock.hw_lock->lock ) || \
dev->lock.pid != current->pid ) { \
DRM_ERROR( "%s called without lock held\n", \
__FUNCTION__ ); \
return -EINVAL; \
} \
} while (0)
causes my lockup problem.
It seems that there should a LOCK which is not set!
Now, i am not so into DRM code so i am asking for help here.
What can be tryed to avoid this problem?
(i have tryed to comment out the macro but i'v got a nice
Mar 6 20:07:08 shimitar vmunix: Unable to handle kernel NULL pointer
dereference at virtual address 00000030 ) off course.
