Description of problem:
I pop the first CD into the drive and boot the machine. It hits the
ldlinux screen and I whack the enter key to start the installer. Standard
messages scroll by until I get to the following lines:
and then the system locks up tight. I've tried various combinations of
no-probing, expert and text-only options. The disk works fine in both of
my Athlon systems and on a Dell machine at work. The system that I'm
having trouble with is a VALinux 1000 machine (quite similar to the IBM
Netfinity 4000r) - dual processor P3 with the Symbios Logic SCSI controller.
Steps to Reproduce:
1. Insert CD into the drive and turn the power on
2. Hit enter at the LDLinux screen
3. Wait for the lockup ;)
Please look at VC3 (switch over as soon as you can) and let us know the last few
lines that get printed out. Also VC4 is helpful.
We (Red Hat) should really try to fix this before next release.
It appears to have something to do with USB. What shows up on VC4 prior to the
<6>usb.c: registered new driver usbdevfs
<6>usb.c: registered new driver hub
<6>usb-uhci.c: $Revision: 1.259 $ time 15:38:25 Jul 24 2001
<6>usb-uhci.c: High bandwidth mode enabled
<6>usb-uhci.c: USB UHCI at I/O 0xef80, IRQ 9
<4>usb-uhci.c: Detected 2 ports
On VC3 it says:
* looking for usb controllers
* found USB controller usb-uhci
* going to insmod usbcore.o (path is NULL)
* going to insmod usb-uhci.o (path is NULL)
On the theory that USB was causing the installer to hang, I went into the BIOS
and disabled USB. The installer came up just fine at that point. That's all
well and good, but I'm using a USB keyboard and mouse on it ... ;) So, another
reboot to re-enable the USB and to try fiddling with some of the USB settings in
the BIOS. Enabling or disabling "Port 64/60 Emulation" didn't do anything for
me, nor did enabling or disabling "USB KB/Mouse Legacy Support". So, to make
the installer happy, I scrounged up an old PS/2 keyboard and mouse and used that
Once installed, USB functions just fine, it's just the installer that has heartburn.
If you have usb enabled in the bios, and boot with 'nousb' on the command line
when booting the installer, does it not hang? I know this will not let you use
the keyboard and mouse, just want to check this helps with the hanging.
Doing a "linux nousb" at the ldlinux prompt made the load up just fine.
Ugh, that english doesn't parse very well. s/made the load up/made the
installer load up/ (duh)
It occurs to me that if it'd be helpful to see the machine, I live in Durham and
it wouldn't be a problem for me to bring the machine by some time. Besides,
it'd be fun to get the nickel tour. :)
There are known problems with some machines and USB in the kernel, which is why
we have the 'nousb' option.
Passing to the kernel team, this appears to be related to drivers and hardware.
I have two questions for the requestor.
1. It was indicated that switching VTs worked.
When switching to tty2, did the bash prompt respond to <Enter>?
2. Did hitting <alt>-<sysrq>-P produce anything?
It may be disabled sometimes.
I assume you may test this without destroying the current
installation because the hang happens very early.
Sorry it took me so long to check this ...
In regards to the first question, the shell is never launched because the hang
occurs during the rinning of /sbin/loader. Once the system hangs, hitting
alt-sysrq-p has no effect.
Gah, I can spell, really I can. s/rinning/running/
The note of 08/07 says "once [OS] is installed, USB works fine".
That means the difference between i386-BOOT and i686smp kernels
Can you try "nousb" with regular reboot and see if the thing hangs
(or better yet, use i686 kernel that is installed by default
even on SMP machines)?
BTW, Never enable "Port 60/64 Emulation" - I do not guarantee
that psaux driver is compatible with all [broken] SMM emulators
that BIOS vendors ship.
Oops, I am sorry - I meant "nosmp", not "nousb".
See if it locks in UP mode.
Aha! That's what that port 64/60 jazz is all about! :) Thanks for that tidbit.
Booted the system up off the harddrive and told Grub to load the
single-processor kernel. System hung when it went to initialize the USB
Just tried the Rowswell 2 release, same issue when using the uni-processor
kernel. Installer also still hangs when not specifying the nousb parameter.
Since you have the hardware, we have to debug on your
box, if you are interested in pursuing it.
Can you compile kernels, or do you need RPMs from me?
Also, please verify for me that you box is not based
on 440GX chipset.
I'd be happy to help debug. It's not a problem to compile kernels either. :)
The board is based on the 440GX chipset for what it's worth.

VA patch (for 2.2 kernel!)
Could you try adding "apic" to the syslinux prompt ?
eg type "linux apic" on the very very first screen ?
The apic option works great! The installer booted right up and detected my USB
I discussed it with the team and we decided not to try
to pull VA fix. It is a vendor specific workaround for
a broken hardware. Also, "apic" works.
