Hi Josh,

So adding config DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT to v5.19-rc2 got it
working again for me on arm64. However commit dcea997beed6 ("faddr2line:
Fix overlapping text section failures, the sequel") seems to be broken
for me, below - this first appeared in rc3. Any idea what the issue
could be?

$./faddr.sh hisi_sas_sata_done+0x8/0x38
hisi_sas_sata_done+0x8/0x38:
fs mm ??:0

Thanks,
John
