As promised the exact errors reported (pulled from /var/log/dmesg)
...
hda: ST310212A, ATA Disk Drive
hdd: IRQ probe failed (0xfef8)
hdd: IRQ probe failed (0xfef8)
hdd: no response (status = 0x80), resetting drive
hdd: IRQ probe failed (0xfef8)
hdd: no response (status = 0x80)
ide0 at ... on irq 14
...
Looking at this it may not have anything to do with my anomolies.
My drive access light remains solid, but the system monitor does not seem to reflect
this activity. My CDROM seems to be in and out of access, the light comes and goes,
but no /dev/cdrom device exists and I'm not able to mount it.
This is the most disturbing as I can't seem to figure out what took place overnight to
make it "disappear."
Thanks for any help anyone can provide.

Subject: lost /dev/cdrom and IRQ probe anomolies -- please help.
A couple of things happened overnight...
I had need to load a RPM and attempted to open the CDROM tray
% sudo eject /mnt/cdrom
Well this failed. I could "feel" the drive spinning. So I tried
% sudo umount /mnt/cdrom
This didn't seem to help so I thought... okay, I'll reboot.
Upon rebooting the system briefly hung at the IRQ probe stating
hdd: IRQ probe failed
hdd: IRQ probe failed
hdd: ... resetting drive
(I can post the exact statements as soon as I find the log file with this
information...)
The system paused and then began booting with a green light ("OK") down the board.
Upon reboot, /dev/cdrom and /mnt/cdrom both vanished into the ether. Additionally, the
drive access lights are both light solid (cdrom and hdd).
System performance seems fine and services are running as expected.
Are there any suggestions for further investigations I can take to track down the
reasons for both the IRQ probe failures and the missing /dev/cdrom device? The missing
/dev/cdrom is the most disturbing... I just used the CDROM two days ago, and now it's
gone. (It's possible that the drive is dead, the machine itself is old, but certainly
not at MTBF.)
Warmest Regards,
Tim
