--- Begin Message ---Package: udev Version: 175-7.2 Severity: normal When attempting to write an ISO installer image to a USB stick, at some point there is an unkillable blkid process (state: uninterruptible sleep) and syslog gets spammed with the following message once every second: # dd if=debian-7.0.0-i386-DVD-1.iso of=/dev/sdh bs=4k syslog output: ... May 6 19:49:10 desktop udevd[6290]: timeout: killing '/sbin/blkid -o udev -p /dev/sdh' [8357] May 6 19:49:11 desktop udevd[6290]: timeout: killing '/sbin/blkid -o udev -p /dev/sdh' [8357] May 6 19:49:12 desktop udevd[6290]: timeout: killing '/sbin/blkid -o udev -p /dev/sdh' [8357] May 6 19:49:13 desktop udevd[6290]: timeout: killing '/sbin/blkid -o udev -p /dev/sdh' [8357] May 6 19:49:14 desktop udevd[6290]: timeout: killing '/sbin/blkid -o udev -p /dev/sdh' [8357] ... # ps -C blkid -o pid,state,user,group,etime,cls,cmd PID S USER GROUP ELAPSED CLS CMD 8357 D root root 59:51 TS /sbin/blkid -o udev -p /dev/sdh ^^^ ^^^^^^^ When the write finishes, this gets logged to syslog: May 6 20:11:31 desktop udevd[6290]: '/sbin/blkid -o udev -p /dev/sdh' [8357] terminated by signal 9 (Killed) May 6 20:11:31 desktop udevd[6290]: timeout 'udisks-part-id /dev/sdh' During this time, I/O performance to the device severely suffers -- the ISO write takes about 90 minutes to complete instead of the usual <10 mins. I wasn't sure whether this was a bug in how udevd calls blkid, or in blkid (from util-linux), or udisks-part-id (from udisks), so please reassign as necessary.
