[Bug 565172] Re: BUG: unable to handle kernel paging request at f76ff01c

[Randall Smith]

There's an interesting comment in /usr/lib/pm-utils/sleep.d/90clock

#!/bin/sh
# Synchronize system time with hardware time.
# Modern kernels handle this correctly so we skip this hook by default.

. "${PM_FUNCTIONS}"

suspend_clock()
{
    /sbin/hwclock --systohc >/dev/null 2>&1 0<&1
}

resume_clock()
{
    /sbin/hwclock --hctosys >/dev/null 2>&1 0<&1
}

So this would imply that at some point, the kernel did not handle this
correctly.  Maybe there was a regression.

Just as a reference so that everyone reading this and setting this
option knows what they're doing to their system:

       NEED_CLOCK_SYNC
           If your system clock drifts across a suspend/resume or
           hibernate/thaw cycle, you should set this to true. This will cause
           pm-utils to synchronize the system clock whenever going through a
           sleep/wake cycle at the expense of making suspend/resume take
           longer.
