I think it's compact flash cards in PATA adaptors we're talking about. lsusb in the working Ubuntu shows me a "Standard Microsystems Corp. 9-in-2 Card Reader" and there are ports on the desktop computer's front panel to insert CF, MS/SD/MMC and SM/XD cards. There's also a docking port with 3 connections on the top of the computer to connect a MEDION external eSATA drive, but there's no external disk connected to it, so I don't think that's one of the sd's I also didn't connect no usb disk or memory stick. Also, how are you able to do an ls on /dev? How are you > booting this machine to see this? When the machine boots, it first loads GRUB. 64Studio is the default kernel in the list because it's the last distro I installed. When I choose 64studio to boot, I first get the error warning: PCI: BIOS Bug : MCFG area at e0000000 is not E820-reserved PCI: Not using MMCONFIG Loading please wait.... _ (blinking underscore for a while) Then I get the same ase Dave reported: Check root= bootargs cat /proc/cmdline or missing modules, devices: cat /proc/modules ls /dev. (initramfs) here I do ls /dev I would also be interested in the output of the following: > > for each in `ls /dev/*` ; do parted $each print ; done > > You may need root privileges for that command. OK, I will try that now, but I don't think root privileges will be needed because there's no user logged in yet, it's "busybox", (initramfs), what's the correct name for that "application" ? > > I've been checking launchpad for related bugs and found > > [REGRESSION] No disk drives in /dev/disk after upgrading to Intrepid > > <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/267634> > > looking imho similar to the one we're having here, and the fix is added: > > > > Colin King wrote on 2008-09-24: > > <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/267634/comments/3> > > > > Commit a2bd7274b47124d2fc4dfdb8c0591f545ba749dd introduced this bug, and > > Linus has now reverted it > > > > (commit b4609472116bb806a95e98d04767189406c74c70).

According to Free: > "The problem is that the 3.0 alpha release still uses the 2.6.21 > kernel..." so we are not dealing with apples to apples here. Thanks for the coment, but , I was thinking that too, I just don't know where to find out when "Commit a2bd7274b47124d2fc4dfdb8c0591f545ba749dd" had been applied (and how it introduced the bug). If this was done in the 2.6.21 kernel, we would be dealing with apples to apples imho. So now I still think it could be relevant. > 64Studio 3 > alpha uses 2.6.21 and the latest Ubuntu kernel is 2.6.27-9.19 I suspect > that the newer udev/hotplug userspace apps that ship with Ubuntu may be > acting weirdly with such an old kernel. So if I understand this correctly, to get it working, these userspace apps should be modified/rewritten to work also with the older kernel, for 64studio and other distro's who still depend on the 2.6.21 kernel. Or use some sort of adaptor or "protocol" convertor ? Anyway, I'll try the for each in 'ls /dev ... thing now .. Cheers Peter
