Thanks Jeff,
I've just applied that patch successfully.
Let me repeat the tests I made before, once the patch is working.
Note that I've applied that patch to my 2.6.24 kernel tree (to the
ubd_kern.c source file). That guest kernel have been already patched
and compiled using skas4 (compiled again with your patch). I told you
only to clarify what is the situation.
Results:
Scenario 1:
it happens the same thing I previously described.
~# dmesg | grep cdrom
Kernel command line: ubd0=rootfs.debian.etch ubd1=swapfs.debian
ubd2=/dev/cdrom eth0=tuntap,,,192.168.1.101 mem=512M root=98:0
Couldn't open "/dev/cdrom", errno = 123
I can also read some significant messages during the boot process:
Initializing software serial port version 1
console [mc-1] enabled
ubda: unknown partition table
ubdb: unknown partition table
Couldn't open "/dev/cdrom", errno = 123
Failed to initialize ubd device 2 :Couldn't determine size of device's file
The /dev/ubd2 node seems to be present as well as for the /dev/ubdc.
Scenario 2:
I get the same message above as regard boot messages. But I still get these:
~# eject /dev/ubd2
not an sg device, or old sg driver
eject: unable to eject, last error: Invalid argument
~# dmesg | grep cdrom
Kernel command line: ubd0=rootfs.debian.etch ubd1=swapfs.debian
ubd2=/dev/cdrom eth0=tuntap,,,192.168.1.101 mem=512M root=98:0
2.1) Same result I posted last time.
2.2) Same result I posted last time.
Let me give you the strace eject /dev/ubd2 again, it may helps you to
understand.
(I don't know if it's the same strace I posted before)
