Please follow http://pcsclite.alioth.debian.org/pcsclite.html#support to provide mode details. Collected now some debug output, but I don't like to attach it here because of potential privacy issues. Whom should I send the package, perhaps gpg encrypted. You can send it to me at ludovic.rousseau My PGP key is available at http://ludovic.rousseau.free.fr/gpg_key.txt I do not see anything strange in the pcscd logs. Only strace log shows a log of: 28954 poll([{fd=5, events=POLLIN}, {fd=4, events=POLLIN}], 2, -1) = 1 ([{fd=4, revents=POLLIN}]) 28954 recvmsg(12, 0xb74b5298, 0) = -1 EAGAIN (Resource temporarily unavailable) 28954 poll([{fd=5, events=POLLIN}, {fd=4, events=POLLIN}], 2, -1) = 1 ([{fd=4, revents=POLLIN}]) 28954 recvmsg(12, 0xb74b5298, 0) = -1 EAGAIN (Resource temporarily unavailable) Do you see the high load all the time or only when you initiate a ssh connection? The load of pcscd also includes the load of the smart card reader driver which includes the load of libusb. What version of libusb is used by /usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Linux/libccid.so? Use ldd -r /usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Linux/libccid.so to find the filename. Regarding the load it is very strange. In the beginning of usage of the smartcard everything works like expected, even if I hibernate the PC for some time. Then after one of the next wakeups pcscd suddenly turns mad and is under load, never returning from the state until the daemon is killed. Will try to track when it starts turning mad. $ ldd -r /usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Linux/libccid.so linux-gate.so.1 => (0xb7716000) libusb-1.0.so.0 => /lib/libusb-1.0.so.0 (0xb76cb000) undefined symbol: log_xxd (/usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Linux/libccid.so) undefined symbol: log_msg (/usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Linux/libccid.so) libpthread.so.0 => /lib/libpthread.so.0 (0xb76b1000) libc.so.6 => /lib/libc.so.6 (0xb74f2000) libudev.so.1 => /lib/libudev.so.1 (0xb74df000) /lib/ld-linux.so.2 (0xb7717000) libdl.so.2 => /lib/libdl.so.2 (0xb74d9000) librt.so.1 => /lib/librt.so.1 (0xb74d0000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb74b3000) $ rpm -qf /lib/libusb-1.0.so.0 libusbx-1.0.16-3.fc19.i686 It might also be a libudev (or kernel) issue. Have a look at this other bug "pcscd: 100% CPU usage in hotplug_libudev.c after suspend/resume" http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=718473 This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. Problem still occurs from time to time on fc21, mostly after wakeup from hibernate. This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'.
