Public bug reported:
- Hardware: 08ec:0015 M-Systems Flash Disk Pioneers Kingston DataTraveler ELITE
- The trouble doesn't exist with other USB drive I have.
- The trouble is reproducible on every single computer: it isn't related to my
hardware confirguration
udisk --monitor output lots of "changed:
/org/freedesktop/UDisks/devices/sdc" before "added:
/org/freedesktop/UDisks/devices/sdc1".
I tried to change sdc1 partition type from 6 (fat16) to b (fat32)
because I'm not sure of the filesystem but that doesn't change anything
about udisks-daemon CPU usage and delay before be able to mount the
partition.
I'm using Ubuntu 12.04 but the bug has existed in previous version too.
This bug may be related to #726814.
