--- Comment #237 from Mark Millard <marklmi26-f...@yahoo.com> ---
(In reply to Mark Millard from comment #235)
Old comments that reference one or both of:
0xFFFFF80000000000 (also known as 18446735277616529408)
0xFFFFF80000000007
comment #44
comment #94
comment #148
Example from 44 (that 94 references):
#8 vtozoneslab (va=18446735277616529408, zone=<optimized out>,
slab=<optimized out>) at /usr/src/sys/vm/uma_int.h:635
#9 free (addr=0xfffff80000000007, mtp=0xffffffff824332b0 <M_SOLARIS>)
at /usr/src/sys/kern/kern_malloc.c:911
#10 0xffffffff8214d251 in nv_mem_free (nvp=<optimized out>,
buf=0xfffff80000000007, size=16688648)
at /usr/src/sys/contrib/openzfs/module/nvpair/nvpair.c:216
Example from 148 (an nfsd process context):
#7 0xffffffff80c895cb in atomic_fcmpset_long (src=18446741877726026240,
dst=<optimized out>, expect=<optimized out>)
at /usr/src/sys/amd64/include/atomic.h:225
#8 selfdfree (stp=stp@entry=0xfffff80012aa8080, sfp=0xfffff80000000007)
at /usr/src/sys/kern/sys_generic.c:1755
#9 0xffffffff80c8866b in seltdclear (td=td@entry=0xfffffe00b52e9a00)
at /usr/src/sys/kern/sys_generic.c:1967
[I'll note that 18446741877726026240 = 0xFFFFFE00B52E9A00 but is likely
from use of dereferencing something based on the 0xfffff80000000007 in
some way.]
The history suggests that 0xfffff80000000007 (or 0xfffff80000000000)
corruption is not limited to a specific place.
