It causes very weird problems. Thanks to Joe for tracking them down.] With the added postfixes that LTO adds for local symbols, the longest name in the kernel overflows the namebuf[KSYM_NAME_LEN] array by two bytes. That name is: __pci_fixup_resumePCI_VENDOR_ID_SERVERWORKSPCI_DEVICE_ID_SERVERWORKS_HT1000SBquirk_disable_broadcom_boot_interrupt.1488004.672802 Double the max symbol name length.
