I recently installed a Smart and Friendly SpeedWriter-RW (4424) CD_RW
drive
in my system (its an IDE drive, not SCSI).
With kernel 2.2.5; I experienced random and frequent crashes; I was not
able to recover any panic messages or OOPS's; nor did the logs have
anything
enlightening. The system just hung dead.
I upgraded to 2.2.15, and the crash behavior went away; however I am
seeing
momentary "hangs" similar to what others have been reporting here in the
list. These hangs occur whether or not I'm using the new driver or
not--
they occur even if I pass "hdd=none" (its the slave on the secondary IDE
channel) to LILO at boot time. The log file gets filled with all sorts
of DMA timeout errors.
My system is as follows:
* AMD-K6 200, SuperMicro P55MMS motherboard, 64MB RAM (time for me to
upgrade, I suppose...)
* IDE only; with the following devices:
* primary IDE master (hda) is Quantum Fireball HD, 4.2Gb
* primary IDE slave (hdb) is Toshiba 32x CDROM
* second. IDE master (hdc) is another Quantum HD, 10.3Gb
* second. IDE slave (hdd) is the aforementioned CDRW.
* Red Hat Linux 6.1, with kernel changed to 2.2.15 (no patches) as
mentioned above.
* Nothing else out of the ordinary....
I'm posting this mainly as a bug report; as I suspect it is a kernel
issue
and not anything else. The drive works fine under Win95.
My dmesg file from my last boot:
