Hi to all!

After some months without using the machine and waste some time to bring the pc running again, I got this error trying load linuxcnc.

as well as in the output of the shell command 'dmesg' and in the terminal



Any help will be welcome,

Looks like a bad bit on the PCI interface.

If the card has not been mechanically damaged, the most likely
cause would be dirty contact fingers on the 5I25 or dirty slot
contacts on the PCI slot.

As a first attempt to fix, I would clean the 5I25 contact fingers
and PCI slot contacts with 99% IPA or other contact cleaning solution.

After this make this thread I remove the card for inspection, and when I plugged it again it works fine. Somehow the pci slot develop a bad connection.

Solved for now! Thanks
