Are these Kernel errors cause for concern?

Can anyone help me decipher this log entry?

WARNING: Kernel Errors Present
end_request: I/O error, dev hdc, sector...: 3 Time(s)
vesafb: probe of vesafb0 failed with error -6...: 1 Time(s)

The thing is, here's my partition info:

There is no hdc. Why the Kernel complaint? Thanks for any help.

hdc: probably cdrom/dvd drive. Many reasons can cause this error, unreadable cd in drive, for example.

vesafb0 : problems initializing framebuffer. Hard to say why (info about your graphic card should help).

Thanks for your help, Mara! Can you suggest a way in which I might obtain useful information about the video (it's onboard)?

Regarding the HDC error: might NO disk in the optical drive cause the error?
Thank you again.

Rob

Onboard video, so
cat /proc/pci
should give all the info. The command shows all devices (pci and agp), in fact, so the list may be long. Look for video card entry, you should find it easily. If not, please post output (removing obvious cases you can find like NIC etc).

hdc: I'm not 100% sure (don't have such messages in my logs), but it seems to be possible. The error would be serious with hard disks, with cdroms it's not very important.

Hi Mara,

I don't see any indication regarding which device is which. Here's the output:

After looking onto certain databases it looks that the graphic card entry is
[code] Bus 0, device 1, function 0:

and the card is Intel Corp. 82810E DC-133 CGC [Chipset Graphics Controller] (Intel's, build-in).
The right driver for it is i810 (standard, included).

Wow. Thanks! I'd be curious to know how you found that info....

I swapped out the optical drive for another (I've got a lot of spare parts around), and got the same error, but the drive seems to work fine once the system has booted. I'm just going to ignore the hdc error I suppose.

Anyway, is there any chance that the vesafb error is caused by fact that I don't have a monitor plugged into this box? (I interact with it through SSH and occasionally VNC.)

Did you ever figure yout a solution?

I have the same error in my syslog.

My system also has an onboard video card with no monitor attached to it.
output of cat /proc/pci is:

norbi99, in your case the right driver is also i810. Do you use it?
