I have recently installed a 8X IDE CDROM drive from Samsung in my old 486. However, when I mount or sccess it, everything will typically work fine for a few minutes, and then the CDROM craps out, making loud and mysterious noises, starting and stopping the engine every few seconds etc. Sometimes, system performance goes down so much that I cannot reboot my machine cleanly. Occasionally, this porblem will even survive a warm reboot. I have experienced this problem on both 2.2.10 and 2.2.13 kernels.
Does anyone have any ideas on what to try? I've done some dejanews searches etc and have not come up with anything, although the name Samsung seems to crop up a lot in connection with CDROM problems.
