Looks like psav->FBBase gets set to 0 here, and is not initialized again:

Any time I end the X session, X crashes. It can be reproduced simply by running: X DISPLAY=:0 xset q Backtrace: #0 0xb7d5c34c in memcpy () from /lib/tls/i686/cmov/libc.so.6 #1 0xb7bc9ba8 in SavageLoadCursorImage (pScrn=0x820dce0, src=0x8387ee0 "\017�) at savage_cursor.c:214 #2 0x080ff4e6 in xf86SetCursor (pScreen=0x82bd718, pCurs=0x839a1c8, x=512, y=384) at xf86HWCurs.c:148 #3 0x080fec4b in xf86CursorSetCursor (pScreen=0x82bd718, pCurs=0x839a1c8, x=<value optimized out>, y=<value optimized out>) at xf86Cursor.c:325 #4 0x0812ac54 in miPointerUpdate () at mipointer.c:358 #5 0x0812ad69 in miPointerDisplayCursor (pScreen=0x82bd718, pCursor=0x839a1c8) at mipointer.c:181 #6 0x081434fe in CursorDisplayCursor (pScreen=0x82bd718, pCursor=0x839a1c8) at cursor.c:136 #7 0x08167367 in AnimCurDisplayCursor (pScreen=0x82bd718, pCursor=0x839a1c8) at animcur.c:234 #8 0x0809766b in DefineInitialRootWindow (win=0x825f5c8) at events.c:2133 #9 0x0807673a in main (argc=1, argv=0xbf80aae4, envp=0xf000f065) at main.c:431 The call to "memcpy" looks like this: memcpy(psav->FBBase + psav->CursorKByte * 1024, src, 1024); where "psav->FBBase" is 0. (The backtrace is actually from xorg-server 1.3.0 and xf86-video-savage-2.1.2, but I wasn't sure what to select in the report. Xorg 7.2 crashes the same way, though.)
