[Xen-devel] timer_interrupt problem

["Guy Zana" <guy@xxxxxxxxxxxx>]

Hello, I compiled Xen unstable changeset 13568 (PAE) and encountered some problems.

Test machine: IBM ThinkPad T60, latest BIOS, running FC6.

 

1. xm dmesg shows the following errors:

* APIC error on CPU0: 00(40)

* APIC error on CPU0: 00(40)

* platform_hypercall.c:142: Domain 0 says that IO-APIC REGSEL is good

* irq.c:438:d0 Cannot bind IRQ 2 to guest. In use by 'cascade'.

 

2. The console keeps showing the following message:

"Timer ISR/[0,1]: Time went backwards: delta=NEGATIVE_NUMBER ..." (producted in time-xen.c (kernel sparse) line:651)

Seems like a sync problem...

 

3. The system behaves like it misses interrupts, the mouse and keyboard have some lags...

I guess that this happens because of the new kernel (2.6.18),

I didn't experience these problems in kernel 2.6.16.33

 

4. xend.log shows alot of XenAPI functions that are missing... for example, "API call: VIF.get_io_read_bks not found".

 

Any idea on how to fix it?

 

Btw: I compiled the same changeset/kernel on an Intel vPro computer and it worked perfectly.

 

Thanks in advance,

 

Guy Zana.
