According to 'man msgrcv':

Bug: The kernel only returns a message if its type is 1; other messages with
type < abs(msgtype) will never get returned.
Fix: After having traversed the list to find the first message with the
lowest type, we need to actually return that message.
Sorry for the breakage. Needs to go to -stable as well.
Do you know which commit caused the regression? That would help those
who wish to fix up their kernels.
Commit daaf74cf0867e3042090d56d10b194d6265b4684,
ipc: refactor msg list search into separate function
introduced this regression.
