I am having difficulty booting 2.4-based Linux kernels on my
Netpliance I-Opener. The Linux 2.4 TODO list has the following entry:
IDE fails on some VIA boards (eg the i-opener) (reported fixed by Konrad
Stepien)
This issue is not really "fixed" as reported in the TODO. Mr. Stepien
has indicated to me in e-mail that his problem went away on a
non-i-opener motherboard with a VIA chipset when he upgraded to 2.4.0.
There is a long history of this issue. There was a patch posted to
the linux-kernel mailing list that allegedly solved the problem:
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0009.3/1218.html
This patch was reposted here:
http://boudicca.tux.org/hypermail/linux-kernel/2000week51/0317.html
The patch fixes a bug in the way the IDE probing code handles flash
disks. The bug occurs when there is one (and only one) hard disk
attached to the IDE connector on the I-Opener motherboard.
Here is what happens when I boot 2.4.2 without the patch:
...
VP_IDE: ide controller on pci bus 00 dev 39
VP_IDE: chipset revsion 6
VP_IDE: not 100% native mode: will probe irqs later
hda: ibm-dyka-22160, ata disk drive
hdb: sundisk sdtb-128, ata disk drive
hdb: set_drive_speed_status: status 0x51 { driveready seekcomplete error }
hdb: set_drive_speed_status: error=0x04 { DriveStatusError}
ide0: Drive 1 didn't accept speed setting. Oh, well.
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdb: 31360 sectors (16 MB) w/1KiB Cache, CHS=490/2/32
Partition check:
hdb: hdb1 hdb2 hdb3 hdb4
floppy0: no floppy controllers found
...
VFS: Cannot open root device "301" or 03:01
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 03:01
... and here is what happens when I boot it *with* the patch:
...
VP_IDE: ide controller on pci bus 00 dev 39
VP_IDE: chipset revsion 6
VP_IDE: not 100% native mode: will probe irqs later
hda: ibm-dyka-22160, ata disk drive
hdb: sundisk sdtb-128, ata disk drive
hdb: set_drive_speed_status: status 0x51 { driveready seekcomplete error }
hdb: set_drive_speed_status: error=0x04 { DriveStatusError}
ide0: Drive 1 didn't accept speed setting. Oh, well.
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: 4233600 sectors (2168 MB) w/90KiB Cache, CHS=525/128/63, UDMA(33)
hdb: 31360 sectors (16 MB) w/1KiB Cache, CHS=490/2/32
Partition check:
hda: hda1 hda2
hdb: hdb1 hdb2 hdb3 hdb4
floppy0: no floppy controllers found
...
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 176k freed
<slient hang>
You'll notice that the kernel sees hda's geometry and partitions after
the patch is applied, but I am still unable to get my i-opener to
boot. I have tried the following kernels to no avail: 2.2.16, 2.4.0,
2.4.1, 2.4.2, 2.4.3pre3. My installation method was to install Redhat
7.0 and upgrade my kernel to 2.4.x. Yes, I got the latest modutils.
I have tried the following LILO parameters without success:
hdb=noprobe
hdb=flash
hdb=none
hdb=noprobe
After doing a little debugging with the patch enabled, it appears as
if the execve("/sbin/init") in main.c's init() is never succeeding. I
tried passing "init=/bin/sh" to LILO and I still get the "silent
hang".
Note: all of the above kernels *will* boot when I plug the harddisk
into my ATX clone machine, but they won't boot on my i-opener. I
*have* been successful in getting the i-opener to boot when I use an
old 2.0.35 kernel. But I need USB mass storage to turn my box into an
MP3 player, so I need a 2.4 kernel. So the problem is not the
harddisk because it boots in other computers, and it's not the BIOS
because I can boot older 2.0 kernels. I am hypothesizing the problem
is at the driver/filesystem layer.
There are many people in the same predicament as I am. The i-opener
newsgroups are littered with people who are unable to get 2.4-based
kernels to boot on their machines. Any help would be appreciated.
