SubjectRe: cdrecord has problems under 2.3.12

From tmolina@home.com Mon Aug 2 21:15:21 1999

>[1.] One line summary of the problem:
>cdrecord has problems under 2.3.12

>[2.] Full description of the problem/report:
>cdrecord starts recording, and after some variable amount of time it
>errors out. See section 7.5 for program output at point of failure. It
>appears to my untutored eyes to be related to timing or buffering since
>the program output says loss of streaming. I made three coasters trying
>to determine if the problem was with hardware or media. Even with no
>user processes running except cdrecord, the problem persisted. Booting
>back to a stock 2.2.10 appeared to solve the problem and allowed me to
>record the cd. Any pointers in diagnosing the problem would be
>appreciated.

>[4.] Kernel version (from /proc/version):
>Linux version 2.3.12 (root@wr5z) (gcc version egcs-2.91.66

It may be:

- A Kernel scheduling bug

- A Kernel memory management bug (less probable)

- SCSI disconnect/reconnect disabled for some reason.
