Subject: [linus:master] [kallsyms] 30f3bb0977:
BUG:sleeping_function_called_from_invalid_context_at_kernel/kallsyms.c
Greeting,
FYI, we noticed BUG:sleeping_function_called_from_invalid_context_at_kernel/kallsyms.c due to commit (built with gcc-11):
commit: 30f3bb09778de64ef9f23fb4bb5f868c4728a071 ("kallsyms: Add self-test facility")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[test failed on linux-next/master e45fb347b630ee76482fe938ba76cf8eab811290]
in testcase: boot
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 16G
