NASLite Network Attached Storage

spurious 8259A interrupt: IRQ7.

I see this on my console.

what does it mean?

should I worry about it?

it may be related to my 3com PCI NIC, because I was getting a (different) reoccurring error before, when moving large files between two drives on my NASLite box, and I swapped NICs to resolve that error message. sorry, I do not recall what the other error message was, with the other NIC - I haven't seen it since swapping with this 3com.

I have onboard sound, onboard serial, onboard parallel disabled.

brand new NASLite+ 1.5 install.

thanks in advance

Well,

Let's start with what's associated with IRQ7. Normally that's associated with the LPT port, which is not supported by NASLite. You should probably disable all unnecessary hardware in the BIOS and see if the problem persists. If you are still having problems, then it will be helpful if you post the system log from the Info share. That will eliminate most of the guess work.

Hope that helps.

Thanks for the prompt response, Tony. The parallel port was already disabled in the BIOS. My system log is below. FYI, regarding the ext3 message at the bottom, I have a WD 200 GB hard drive mounted currently that's from another Linux box - I'm in the process of moving data from it to the other drives before I have NASLite+ format/error check it. Again, everything seems to be in order, but I dislike error and warning messages. Thanks for the help.

I haven't seen that error message since having NASLite format my third hard drive (instead of mounting the pre-existing ext3 file system) and rebooting. So let's presume this is resolved. I'll reply if that error message presents itself again.
