Public bug reported:
As per bug #185703, on my SONY VAIO CR323 laptop hibernate is very slow,
even with the 2.6.27 kernel.
While I appreciate Linux is not Windows and does not aim to be,
comparisons should give an indication of what the hardware is capable
of. Hibernate in Windows takes approximately 7 seconds on this machine.
Under Kubuntu Linux 8.04, from selecting "Suspend to Disk" in
Knetworkmanager to the machine actually powering down takes 1:14
seconds. Interestingly enough, the HDD activity light is only on for 11
seconds of this time. Would be very interesting to know what it is doing
for the rest of the time :)
