Hi, After updating to r238120, I get a panic whenever X starts up. It works for a few seconds, then panics. The messages don't look too useful to me, but here they are: Unread portion of the kernel message buffer: processor eflags = interrupt enabled, resume, IOPL = 0 current process = 3610 (kdm_greet) trap number = 12 panic: page fault cpuid = 0 (kgdb) bt #0 doadump (textdump=dwarf2_read_address: Corrupted DWARF expression. ) at pcpu.h:224 #1 0xffffffff8087ef79 in kern_reboot (howto=dwarf2_read_address: Corrupted DWARF expression. ) at kern_shutdown.c:449 #2 0xffffffff8087f413 in panic (fmt=dwarf2_read_address: Corrupted DWARF expression. ) at kern_shutdown.c:637 #3 0xffffffff80b77d08 in trap_fatal (frame=dwarf2_read_address: Corrupted DWARF expression. ) at trap.c:852 #4 0xffffffff80b78012 in trap_pfault (frame=dwarf2_read_address: Corrupted DWARF expression. ) at trap.c:678 #5 0xffffffff80b777aa in trap (frame=Variable "frame" is not available. ) at trap.c:456 #6 0xffffffff80b62142 in calltrap () at /tmp/exception-vH8hmc.s:179 #7 0xffffffff80b6f6b0 in pmap_enter (pmap=dwarf2_read_address: Corrupted DWARF expression. ) at pmap.c:3587 #8 0xffffffff80adafa0 in vm_fault_hold (map=dwarf2_read_address: Corrupted DWARF expression. ) at vm_fault.c:935 #9 0xffffffff80ad9787 in vm_fault (map=Variable "map" is not available. ) at vm_fault.c:229 #10 0xffffffff80b77f26 in trap_pfault (frame=dwarf2_read_address: Corrupted DWARF expression. ) at trap.c:736 #11 0xffffffff80b77670 in trap (frame=Variable "frame" is not available. ) at trap.c:358 #12 0xffffffff80b62142 in calltrap () at /tmp/exception-vH8hmc.s:179 #13 0x00000008040d7796 in ?? () Previous frame inner to this frame (corrupt stack?) Current language: auto; currently minimal (kgdb) Something I saw in a previous panic made me think this was drm related, but I don't see it in this particular one. Stevehelp
