While burning CDs (in CDRW) using burncd program I was unable to access the CD in the CD reader. The kernel displayed this message: ** -- messages - start vm_fault: page read error, pid 3237 (cp) ... sio0: 538 more interrupt-level buffer overflows (total 538) ... (please refer to the dmesg output for additional messages) ** -- messages - end I faced this problem when I started "burncd" while copying files from CD in the CD reader. The "cp" process (that was running) freezed and I was unable use ctrl+c to cancel (^C just printed). But when the burncd completed, the "cp" process resumed copying files. During the "cp" freeze, the system was OK and I faced no lock-ups. Other processes were fine. In fact, I was running X and was fine. (I successfully reproduced the problem without X) Here is my dmesg: *-- dmesg start --* ...
