Hi, More testing and more problems 8-( Mind you, that is not to say that many things do not work wonderfully, because they do ;-) With regard to point one yesterday about the warm reboot problem, it was suggested that I toggle the PnP BIOS option and retry. Well, I did that and indeed there was a difference. Now the machine never (in my limited testing anyway ;-) hangs after printing 'Restarting system'. Now, instead, it always (same caveat) hangs when trying to initialise the UHCI controller 8-( (usb people can ignore the rest of this message) Moving on (I have reported points four and six against previous 2.4.0 test versions but had no response), 4. I rebuilt the kernel without IDE ATAPI CDROM but with IDE SCSI emulation. echo scsi dump 0 > /proc/scsi/scsi causes an oops. I have not, unfortunately, been successful in my attempts to feed the oops report into ksymoops but I can tell you that it is dereferencing a null pointer and killing the shell. 5. Still with IDE SCSI emulation, I inserted a DVD into my (correctly detected ATAPI DVD-ROM drive) and tried to mount it as UDF. I saw loads of 'attempt to read beyond end of device' messages. Note, however, that I am not entirely convinced that this is a real UDF disk, but how can I tell? I can mount it as iso9660 with no problem. 6. Continuing with IDE SCSI emulation we move onto the parallel port CDROM. With the same commands as yesterday (modprobe friq ; modprobe pcd ; mount /dev/pcd0 /mnt/cdrom ) I see a new message - Stuck DRQ and the disk is not mounted. Additionally, this affects the 'intelligent' eject button in the unit meaning that the only way to extract the disk is to switch off at the wall, then switch back on again and press eject. Attached are snippets from the syslog for items five and six. Thanks, Richard
