hi,
I have 2 problems related to reading IRIX EFS cd's.
-------problem 1:
mounting an EFS cd from my Yamaha CDR-4416S SCSI CDRW consistently causes a lockup when i try to read directory/file data from the CD. I observed this initially with EFS CDR's, and assumed something had gone wrong when burning that CD. But the exact same thing happens with original SGI IRIX media. I have no problems with any of my EFS CDs when accesed from an ATAPI CDROM.
i havn't been able to capture an oops, but the following made it to the remote syslog host:

<box is locked>
------problem 2:
My IDE CDROM under ide-scsi emulation does not like trying to mount EFS CDs, here are the logs of multiple mount attempts:
Oct 31 00:06:50 fogarty kernel: EFS: 1.0a - http://aeschi.ch.eu.org/efs/ Oct 31 00:06:50 fogarty kernel: sr.c:Bad 2K block number requested (0 1) I/O error: dev 0b:01, sector 0 Oct 31 00:06:50 fogarty kernel: EFS: cannot read volume header Oct 31 00:06:53 fogarty kernel: Device not ready.

after this the CDROM behaves strange (gtoaster can't read data track, which it could before), until i put another disk (eg audio) into it first.
-----------------------
result:
to mount an EFS cd i have to use my IDE CDROM in ATAPI mode, as the SCSI CDRW locks the machine.
then to burn an EFS cd i have to reboot and set my ATAPI CDROM to use ide-scsi emulation - if i want to mount the CD for any reason i have to reboot again to get the IDE CDROM back to pure ATAPI mode, then reboot again for ide-scsi to burn a cd... slightly frustrating. :)
