| |
I get a kernel oops while trying to read a SONY CDU33A device, connected via a SoundBlaster 16 ISA card, with kernel 2.4.20 The platform is i586 classic, gcc 2.95.3
In /etc/modules.conf I have:
alias block-major-15 cdu31a options cdu31a cdu31a_port=0x0230
so the driver can be loaded as a kernel module
---------------------------------------------- Command line:
air:~# mount /dev/sonycd /mnt -t iso9660 mount: block device /dev/sonycd is write-protected, mounting read-only
air:~# lsmod Module Size Used by Not tainted cdu31a 22912 1 (autoclean) cdrom 26976 0 (autoclean) [cdu31a] isofs 24704 1 (autoclean) inflate_fs 17920 0 (autoclean) [isofs]

----------------------------------------------
Finally, from /usr/src/linux/.config # # Old CD-ROM drivers (not SCSI, not IDE) # CONFIG_CD_NO_IDESCSI=y # CONFIG_AZTCD is not set # CONFIG_GSCD is not set # CONFIG_SBPCD is not set # CONFIG_MCD is not set # CONFIG_MCDX is not set # CONFIG_OPTCD is not set # CONFIG_CM206 is not set # CONFIG_SJCD is not set # CONFIG_ISP16_CDI is not set CONFIG_CDU31A=m # CONFIG_CDU535 is not set
---------------------------------------------- Same behavior with CONFIG_CDU31A=y BTW Audio CDs can be read without any problem.
Any clue? Thank you.
