We have all the sensors and the data system running in the staging area. We've added one Licor 7500 to what was on the tower, for a total of 4 Licors. The data cables, and Licor power cables to the Licors are different however, since they were left on the tower.
After setting it up, I increased the 4 Licor 7500s to 20 samples/sec at 19200 baud.
The spurious interrupts are happening, but appear to be averaging around 50/sec:
viper_irq_handler: irq=2 spurious= 338001, #/sec=102 viper_irq_handler: irq=2 spurious= 342001, #/sec=106 viper_irq_handler: irq=2 spurious= 343001, #/sec=102 viper_irq_handler: irq=2 spurious= 347001, #/sec=103 viper_irq_handler: irq=2 spurious= 348001, #/sec=101 viper_irq_handler: irq=2 spurious= 352001, #/sec=111 viper_irq_handler: irq=2 spurious= 355001, #/sec=104 root@manitou root# uptime 21:44:36 up 1:43, 1 user, load average: 0.16, 0.11, 0.09
The kernel issues a "spurious" message when they occur more often than 100/sec. 335001 interrupts in 1 hour 43 minutes averages to 57/sec.
