| |
Well, that's not really nice. Something is going bad, but it may be that the official driver as of 2.1.99 also has big problems - more to come on this.
Here are my 1st tests reports:
[note that my drive is a cdu33a, ie. double speed version of cdu31a]
* cd with only a FS
# modprobe cdu31a cdu31a_port=0x340 # modprobe isofs # mount /cdrom # fstab lists iso9660
The drive's LED keeps blinking red/orange, the console is frozen (no console switch, no console spawn, gpm does not respond to mouse moves) - eject button is ignored even after reboot - syscall does not return ?
# cdeject =>OK
* pure audio cd
# cdeject does not complete; sometimes prints a "cannot read TOC" (sic); eject-button can either interrupt cdeject, with "cannot open /dec/cdrom" (occured after such a message), or cause (after several minutes waiting and no response) several "Aiee, killing interrupt handler" intermixed with register dumps containing corrupted date (eg. CPU with a very "high" negative ID on my monoprocessor)
* cd with 1 data track and several sound tracks
# cdeject =>OK like pure FS
# mount same symptoms as pure FS
NOTES
* "eject" under cdctrl behaves like cdeject in all cases
* some operations fail with "cannot open /dev/cdrom", and then all attemps fail with the same message - the eject button is ignored even after reboot
* I'll recompile with DEBUG and see if I can get more precise info
* I've not yet tried to reproduce the old oops, given the number of other problems
