Way back when I first got an X2 they couldn't keep time for whatever
reason. I used to have to add something like "clock=pmtmr notsc" to the
kernel command line to make it behave.
That issue was fixed in a later kernel, but you could start adding clock
options to your kernel command line and pray that one of them jiggles
something in your favor.
A couple from the kernel docs:
clock=[BUGS=IA-32, HW] gettimeofday clocksource override.
[Deprecated]
Forces specified clocksource (if avaliable) to be used
when calculating gettimeofday(). If specified
clocksource is not avalible, it defaults to PIT.
Format: { pit | tsc | cyclone | pmtmr }
clocksource=Override the default clocksource
Format: <string>
Override the default clocksource and use the clocksource
with the name specified.
Some clocksource names to choose from, depending on
the platform:
[all] jiffies (this is the base, fallback clocksource)
[ACPI] acpi_pm
[ARM] imx_timer1,OSTS,netx_timer,mpu_timer2,
pxa_timer,timer3,32k_counter,timer0_1
[AVR32] avr32
[X86-32] pit,hpet,tsc,vmi-timer;
scx200_hrt on Geode; cyclone on IBM x440
[MIPS] MIPS
[PARISC] cr16
[S390] tod
[SH] SuperH
[SPARC64] tick
[X86-64] hpet,tsc
tsc=Disable clocksource-must-verify flag for TSC.
Format: <string>
[x86] reliable: mark tsc clocksource as reliable, this
disables clocksource verification at runtime.
Used to enable high-resolution timer mode on older
hardware, and in virtualized environment.
