Hello All,
I am trying to run some custom created hot swap drivers on a SSOL10.
They were working on SSOL8 and SSOL9 but not on the SSOL10. The
system panics when it try to add/modify a property. It seems that the
reason for this is the ddi_prop_ routines are trying to lock the
dev_info_t member 'devi_lock'. But it is already locked.
Also the problem is happening after several correct executions in the
same path (please see below call stack). And my drivers does not
manipulate the 'devi_lock'.
Kindly have a look at this and advice.
Following is my system configuration.

The system panics with the following when I try to run an hot swap server.
