I note this block in pc-bios/keymaps/en-us with interest:
# evdev 86 (0x56), QKeyCode "less", number 0x56
less 0x56
greater 0x56 shift
bar 0x56 altgr
brokenbar 0x56 shift altgr
That block was added in commit a7815faffb2bd594b92aa3542d7b799cc89c5414 , which I am very suspicious was the cause of this problem. I strongly suspect that removing it will fix the problem. Will test now.
