Dear list
I have a measurement computing 4020 and have just compiled and installed comedi. By trial and error
I am loading these modules:
sync; sync;
/sbin/insmod /lib/modules/2.6.10-1.770_FC3/comedi/comedi.ko
/sbin/insmod /lib/modules/2.6.10-1.770_FC3/comedi/comedi_fc.ko
/sbin/insmod /lib/modules/2.6.10-1.770_FC3/comedi/8255.ko
/sbin/insmod /lib/modules/2.6.10-1.770_FC3/comedi/cb_pcidas64.ko
when I run comedi_config
#/usr/local/sbin/comedi_config /dev/comedi0 cb_pcidas64
my computer freezes hard and a power cycle is required to get it back.
I have this from the message log
Aug 6 13:00:01 valium kernel: comedi0: cb_pcidas64
Aug 6 13:00:01 valium kernel: Found pci-das4020/12 on bus 0, slot 12
Aug 6 13:00:01 valium kernel: ACPI: PCI interrupt 0000:00:0c.0[A] -> GSI 17 (level, low) -> IRQ 177
Aug 6 13:00:01 valium kernel: stc hardware revision 1
Aug 6 13:00:01 valium kernel: irq 177
Aug 6 13:01:12 valium syslogd 1.4.1: restart.
Sometimes the hard crash is immediate - other times there is a fraction of a second before it locks and
comedi_config returns to the command line.
Any clues?
Is this possibly some interrupt problem?, is it worth me shuffling the cards around to get the comedi driver on a different IRQ to the network card ( SysKonnect SK-98xx)?
Thanks,
SA
