This reliably results in "kernel BUG at mm/mmap.c:3412!".
bt below
reliably reproduces as follows: spawn "perf top", hit enter twice to
disassemble a func. tui hangs indefinitely, console shows the splat
below.
I verified going one commit down produces a working kernel.
kernel BUG at mm/mmap.c:3412!

Thanks, I'll drop v3 of the series "Introduce a store type enum for the

Hello,
Thanks for your report. When I run perf top and disassemble a function tui
doesn't hang. In dmesg I see:
[ 17.836399] perf: interrupt took too long (2705 > 2500), lowering
kernel.perf_event_max_sample_rate to 73000
[ 17.837532] perf: interrupt took too long (3561 > 3381), lowering
kernel.perf_event_max_sample_rate to 56000
[ 17.838818] perf: interrupt took too long (4654 > 4451), lowering
kernel.perf_event_max_sample_rate to 42000
[ 17.840267] perf: interrupt took too long (5930 > 5817), lowering
kernel.perf_event_max_sample_rate to 33000
but not the bug that your seeing. Could you send your config file so I could
test with that?
Thanks,
Sid

Userspace is Debian 12 (which may be of significance), but just in
