Thread-topic: timer_interrupt problem
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.
