Bug report FS#36686 with Arch

I would like to get more info on the issue:
a) what version of libfm do you use?
b) is libfm compiled with internal udisks support?
c) do you have any gvfs libs installed?
Thank you very much.
While you don't answer, I would like to notice there was a bug which caused memory corruption, that bug leaded to crash, and that bug is fixed in libfm-1.1.2.2. May be it leaded to your issue instead of crash in your case.
Sorry that I didn't reply the first time, i somehow missed the email alert for the first response.
I will check versions/etc later today.
Thanks!
a) what version of libfm do you use?
[dylan@zenbook ~]$ pacman -Sp libfm
http://ftp.osuosl.org/pub/archlinux/community/os/x86_64/libfm-1.1.2-1-x86_64.pkg.tar.xz
b) is libfm compiled with internal udisks support?
I'm afraid I don't know how to tell. I"m using the vanilla version with arch
https://www.archlinux.org/packages/community/x86_64/libfm/
c) do you have any gvfs libs installed?
gvfs does not appear to be installed, and there does not appear to be a gvfs-libs package for arch. I have now installed gvfs and will test, however.
Thanks!
i installed gvfs using pacman. Restarted and the problem still exists.
Any pointers as to how to find the information you need is appreciated.!
Thanks!
Thank you for your testing. Since issue still happens with gvfs - it is not udisks problem. I suggested you already to upgrade libfm to 1.1.2.2 version, the most probably your problem will be gone.
Problem still appears to persist:
[dylan@zenbook ~]$ pacman -Q libfm
libfm 1.1.2.2-1
[dylan@zenbook ~]$ mount | grep sdc

I'm open to other troubleshooting suggestions...
Thank you very much for your efforts. I would like to get more help from you. That can be done with GDB running in terminal when that CPU eating happens:
gdb pcmanfm `pidof pcmanfm`
you'll get into running application from gdb so you can type a gdb command:
bt full
and let me see that stack trace.
Something i should have mentioned before, I am using the desktop mode for pcmanfm

Thanks for working on this! :)
It is indeed expected, almost everyone uses pcmanfm as desktop manager. :)
Unfortunately the stack trace without debug symbols is almost useless. From Arch people I got the advice - you should rebuild appropriate packages with option 'debug' added into options=... in PKGBUILD file, you would need that for packages glib2, gtk2, and libfm. After that the stacktrace will contain info required for investigation of your issue.
Thank you.
Sorry this took so long;

Thank you very much for the response. One of GTK functions used on eject unfortunately found to be buggy. A workaround on similar issue is added into the libfm Git. I'm afraid there will be no further updates for 1.1.x series so I would suggest you to install Git version of pcmanfm (it is 'pcmanfm-git' in AUR) and check if your issue is fixed, and I hope it is.
I am very confused;
I cannot seem to install the pcmanfm-git with just the libfm-git. It seems to require the libfm-gtk-git.
WIth libfm-gtk-git and pcmanfm-git, i still have the same problem.
Which libfm should I be installing with the pcmanfm-git from aur?
Thanks!
Yes, it is correct - libfm-gtk-git is used for pcmanfm-git, it is Arch-specific naming scheme.
That is weird... nobody else has such problem, I suspect it is some another GTK problem unknown for me and I have no idea how I can help. :(
Did it installed successfully? What versions the About dialog shows you? It should show 1.1.99.3 for pcmanfm and 1.2.0-beta2 for libfm (yes, it should show two numbers).
I have
PCManFM 1.1.99.3
Lightweight file manager
using LibFM ver. 1.2.0-beta2
so it looks like it installed successfully.
Well, I would like you to install debug info with glib2 as I asked you earlier to be able to see more detailed info where it cycles and also see output of 'info threads' in gdb when the issue happens. Would be good if you enter 'continue' (or just 'c') in gdb then <Ctrl>+<C> to interrupt it and check 'bt full' again if it shows the same.
What are the versions of your glib2 and gtk2 packages?
Thank you very much.
It would be good if you could investigate if gvfs that you've installed really mounts your SD (it uses udisks2), not udisks. I suspect it's problem of udisks since debian also got a bugreport for udisks 100% CPU load.

To note; the disk does umount properly before the system hangs.
First. Backtrace lines with "No symbol table info available" are useless. I've asked you few times to install debug info for the glib.
Second. Find which thread consumes CPU (top or whatever can display threads, not only process summary) and do backtrace only on it, please. If need to switch to thread 2 then enter 'thread 2' in gdb.
Thank you very much.
Interesting - i have installed the debug info for glib as far as I know. (built and installed a separate package called glib-debug) Perhaps I am doing it wrong?
I will find how to display threads in top and switch to thread that has high cpu utilization. I then provide bt full on that thread, correct?
I will check again tomorrow and provide output. Sorry for any confusion.
