Bug #1182

Updated by swildner almost 13 years ago

Hi, 

 UP works perfectly, SMP has this intr 11 livelock problem, which slows  
 it pretty down, so that network does not work. I post output of dmesg 
 for both UP and SMP as well as the output of vmstat -vi. Maybe those 
 information are helpful to someone :). I also tried SMP with a recent 
 kernel (the outputs below are of a kernel which is a few month old), but  
 it's even worse; it stops at "intr 7 livelocked limit engaged" during  
 ATA probing. 

 Looking at "vmstat -vi" it's obvious that the problem is with atapci1. 
 Also notably is the huge difference of "irq0: clk", which is ~1600 for 
 UP and ~13000 for SMP. I don't know exactly what rate means here, but 
 if it means interrupts/second and it's the clock interrupt which usually 
 fires at 1000 Hz, then something is seriously wrong. 

 Regards, 

    Michael
