http://bugzilla.opensuse.org/show_bug.cgi?id=945094 http://bugzilla.opensuse.org/show_bug.cgi?id=945094#c4 --- Comment #4 from Mindaugas Baranauskas --- Found, that after pluging USB-key, starts new processes: systemd-udevd (4 instances!) scsi_eh_13 scsi_tmf_13 usb-storage sg_inq "sg_inq" and "usb-storage" are sleeping in disk for a minute. When sg_inq automatically terminates, USB device is notified in desktop. When all 4 instances of "systemd-udevd" terminates also. sg_inq is running as `/usr/bin/sg_inq --export --page=sn /dev/sdc` Found, that /usr/bin/sg_inq exist in "sg3_utils" package. In openSUSE TW:

rpm -q sg3_utils sg3_utils-1.41-1.1.x86_64

In openSUSE 13.1:

rpm -q sg3_utils sg3_utils-1.36-3.4.1.i586

After downgrading sg3_utils version to 1.36 (RPM openSUSE 13.1 repo) fixed lond delay issue just after downgrading. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=945094 http://bugzilla.opensuse.org/show_bug.cgi?id=945094#c13 --- Comment #13 from Jan Engelhardt --- (In reply to Mindaugas Baranauskas from comment #11)

In openSUSE TumbleWeed, After just pluging, and executing, it makes long pause after printing:

open("/dev/sdc", O_RDONLY|O_NONBLOCK

So that means the open syscall takes the time. You tried the different sg3utils variants under different openSUSE versions, which makes me think the change of kernel version is the cause, not sg3utils. -- You are receiving this mail because: You are on the CC list for the bug.
