Hi,
I have a setup of TOI with encrypted swap (dm-crypt), which sometimes
seems to block in atomic copy during resume. The machine is Lenovo x230,
kernel 4.3.3 with custom config (issue described below happened also
with earlier kernels).
Usually I can have some 5 to 7 cycles working fine, but then it
somewhere blocks on resume, so I have to turn off the machine and reboot.
The logs written by the pm-utils show the same modules are loaded on
occasions where the cycle finishes successfully and when it blocks.
From the documentation I see that I have to enable debugging, set
default_console_level to 6.
But which other settings would be suited to have a regular debugging
going on, in particular list which drivers / modules are being suspended
/ thawed before or after the atomic copy etc. My idea is to have some
sort of working debug level that allows day-to-day usage and still gives
enough information when the blocking occurs.
Best regards,
Ulrich
p.s.: Otherwise from this issue I am really happy with TuxOnIce for a
very long time!
