Public bug reported:
Title: 7.0.0-42/43: module loading stalls PID 1 for ~14s at boot
(dbus.service 14s vs 1.3s on 7.0.0-38), ASUS X555BP
Hardware: ASUS X555BP, AMD Stoney (00:01.0) + Hainan (01:00.0), both on amdgpu,
3 GB RAM.
System: Ubuntu 26.04.1, upgraded from 24.04.
Regression: boot is ~10 s slower on 7.0.0-42 and 7.0.0-43 than on 7.0.0-38.
7.0.0-38: dbus.service +1.2 s, graphical.target @28 s
7.0.0-42/43: dbus.service +14 s, graphical.target @37-39 s
During the stall (~11 s to ~23 s) everything is silent (journal and dmesg),
then all
services finish at the same moment. A probe of D-state processes shows:
(udev-worker) in ftrace_free_mem, ftrace_process_locs,
static_call_module_notify, arch_static_call_transform,
alternatives_smp_module_add;
modprobe in ftrace_process_locs; PID 1 (/sbin/init) in text_poke_copy.
I/O pressure is flat during the stall (not a disk problem); SMART is clean.
Not reproducible on 7.0.0-38. Please tell me what else to collect.
