Hi all. Basically it boots from CD fine, but fails to recognise the CD-ROM drive - is it not recognising the IDE controller?
You wont be able to use the cdrom drive for anything else if thats the drive you booted from. Is this what you mean? The OS image will be mounted from the drive, so it wont be separately visible. If you booted successfully, then the drive must of been supported.
Hi.
When attempting to install from the Alternative CD:
(Ubuntu 7.04? Alternate CD? - ('uname -r' gives 2.6.20-15-generic kernel version when booted from the problem CD)) I can start the install process (i.e. choose to install in txt mode, kernel loads, can choose my language OK, detect/configure keyboard OK, i.e. the install process is running), but when I get to 'Detect and Mount CD-ROM' the install cannot proceed with "No common CD-ROM drive was detected".
Some further info I just acquired which I will research later tonight:
From the DMESG output:
" ... scsi3: pata_marvell BAR5:00:04 01:7F 02:22 03:C8 04:00 05:00 06:00 07:00 08:00 09:00 0A:00 0B:00 0C:00 0D:00 0E:00 0F:00 ATA: Abnormal status 0x7F on port 0x0001ac07 scsi4: pata_marvell BAR5:00:04 01:7F 02:22 03:C8 04:00 05:00 06:00 07:00 08:00 09:00 0A:00 0B:00 0C:00 0D:00 0E:00 0F:00 ATA: Abnormal status 0x7F on port 0x0001a807 ... "
lspci | grep Marvell finds: Marvell Ethernet1/RAID/Ethernet2
lspci | grep RAID gives: "02:00.0 RAID bus controller: Marvell Technology Group Ltd. Unknown device 6145 (rev a1)"
Note that all of the above info was from the "2.6.20-15-generic" kernel which I assume is from the Ubuntu 7.04 Alternate CD.
Cheers for any help.
Elroy.
I was just thinking, dangerous I know, could it be part of the same kernel bug that causes 7.04 to fail to mount VCD's Most discs mount OK but with VCD's it seems to suddenly think it is a SCSI drive? A known Feisty bug. I believe it is a kernel issue where they merged SATA and PATA drivers so the PATA won't become unsupported as they become obsolete. David
