Hi,

the problem has disappeared in the last week,
I've seen a series of commits for radeonsi,
but could some developer point out what changes have been done,

which may have corrected a NULL pointer dereference MAPERR at address 0x0 
happening at list_add after a destroy_buffer_locked?


11-27 18:00:55.044  3215  3215 F DEBUG   : signal 11 (SIGSEGV), code 1
(SEGV_MAPERR), fault addr 0x0

addr2list output (when issue was present)

Besides closing this bug, the information is important in order to backport bug
corrections in mesa 17.0.x and mesa 13.0.x
