Posted Three Times - No Responses
I have always received great help from this list in the past but I have
had no responses at all to my current problem. Perhaps hundreds of
people have looked at the postings but had no ideas as to how to solve
the problem. Perhaps everyone is too busy getting ready for the release
of Sarge. Perhaps the answer is so obvious that I should have solved it
myself long ago.
The problem: Every time I must shut down the system it locks up when it
tries to disconnect my Sony USB dvdrw drive.
The Postings: May 17 - USB dvdrw mount point Woes
May 22 - kernel-2.6.8 USB problem
May 31 - Oops when Sony USB dvdrw disconnected.
As noted in these postings I am using 2.6.8 kernel complied from the
latest kernal-source-2.6.8 (so recompiled yesterday after a apt-get
dist-upgrade). I am not using discover or discover1because discover
provides no mount point and discover1 provides /dev/sr0 which only
allows me to mount the device to read data cd's. Without these the
device is assigned /dev/sg0 and works perfectly with both cdparanoia and
cdrecord. Hotplug allows me to connect and disconnect other usb devices
but not the Sony DRX-510UL USB dvdrw drive.
I have no trouble using the device as a USB1 (low speed device) with a
2.4.26 kernel - perhaps because I have append="hdc=ide-scsi" in its lilo
stanza. I have omitted this in the stanza for the 2.6.8 kernel as my
understanding is that it is no longer required. With out the
append="hdc=ide-scsi" line in the 2.6.8 kernel stanza cdrecord -scanbus
finds the Sony drive as 0,0,0 and cdrecord -scanbus dev=ATA finds my cd
drive and my cdrw drive as 1,0,0 and 1,1,0.
As noted in one of the previous postings I have searched the archives
and found some postings which seemed related to this problem but no
solutions that worked for me. If there is something I have missed my
feelings wont be hurt if it is pointed out forcibly - I just need a
solution.
