| |
v4.16 boots cleanly. But with the first bunch of merges (Linus HEAD = 46e0d28bdb8e6d00e27a0fe9e1d15df6098f0ffb) I see a bunch of:
ia64_handle_unaligned: 4863 callbacks suppressed kernel unaligned access to 0xe00000031660fd74, ip=0xa0000001000f23e0 kernel unaligned access to 0xe00000033bdffbcc, ip=0xa0000001000f2370 kernel unaligned access to 0xe00000031660fd74, ip=0xa0000001000f23e0 kernel unaligned access to 0xe00000033bdffbcc, ip=0xa0000001000f2370 kernel unaligned access to 0xe00000031660fd74, ip=0xa0000001000f23e0
The addresses are all 4-byte, but not 8-byte aligned.
Any guesses before I start to bisect?
