Description Alon Rubinstein 2001-07-28 17:17:39 UTC
Description of Problem:
While installing  RedHat 7.1 on a IBM notebook 93G I series, the installer crashes and hangs the 
computer in the " /sbin/installer" stage

How Reproducible:

Steps to Reproduce:
1. insert CD and boot off it
2. chose ANY option in the install ( including ide=nodma)

Actual Results:
a complete hang with no response to any keys whatsoever forcing a cold reset

Expected Results:

Additional Information:
A second before the hang I went to vt3 and vt4 : the hang happenend write after the usb modules 

Comment 1 Brent Fox 2001-07-29 02:02:43 UTC
Do you have any USB devices that you need to use during the install?

Comment 2 Alon Rubinstein 2001-07-29 19:55:20 UTC
No I do not need to use any USB devices during the install. I will need to set a Serial adapter - but 
that could be a post install procedure. The installer crashed both with the adapter connected and 

Comment 3 Alon Rubinstein 2001-07-30 21:17:13 UTC
RH6.2 installs without any problems...

Comment 4 Matt Wilson 2001-08-02 18:20:55 UTC
try booting with "linux nousb" at the boot: prompt

Comment 5 Brent Fox 2001-08-14 03:10:44 UTC
alon, any more info here?

Comment 6 Alon Rubinstein 2001-08-14 09:54:57 UTC
ok.. installing with the nousb did enable finishing the installation. However
teh hang now happens with normal boot too. I can boot with "linux nousb" and it
does not hang. however I have no usb support. I tried to add the module manually
after the boot has finished and it hangs immediately. I am talking about the
ohci module (usb-ohci). this is also the case after a kernel update to 2.4.7 -
exact same hang.


Comment 7 Brent Fox 2001-08-14 15:08:05 UTC
Ok.  The problem seems to be with the USB handling, not the installer.  Changing

Comment 8 Pete Zaitcev 2001-08-20 08:01:24 UTC
See also Bug 51063. Symptoms are similar.

Not marking as duplicate just yet because:
1. A different host controller is used.
2. No USB devices are attached to the laptop.

Comment 9 Pete Zaitcev 2001-09-21 23:35:11 UTC
It is established that 51083 is not a dup, which is good.

Requestor, please attach output from lspci -v.I am afraid it may be ALi OHCI
there (phear!).

Subject: USB lockup on Thinkpad i1300
Date: Sat, 22 Sep 2001 04:45:27 -0500
To: linux-kernel@vger.kernel.org

My thinkpad happily locks up with both 2.4.9 and 2.4.10-pre14 when I
load usb-ohci. Tracing with kdb shows that the system locks up right
after executing this: (usb-ohci.c:2137)

        /* HC Reset requires max 10 ms delay */
        writel (OHCI_HCR,  &ohci->regs->cmdstatus);

Anyone have any idea? The processor apparently never gets to the next

[Cc: me please, I'm not on this list.]

P.S. System chipset is ALi:

        Flags: bus master, medium devsel, latency 32, IRQ 10
        Memory at 82400000 (32-bit, non-prefetchable) [size=4K]

Shares IRQ with cardbus bridge and lcd controller.

Is running self-compiled kernels with patches feasible
on the target machine?

Comment 13 Alon Rubinstein 2001-10-10 20:22:12 UTC
Yes, of course!!

all kernels I run are compiled by me..


Comment 14 David Rasmussen 2001-10-16 19:34:58 UTC
Has any progress been made with this problem? I have the same problem on an IBM 
Thinkpad i1300.

Comment 15 David Rasmussen 2001-10-16 19:53:25 UTC
I forgot to add: I will help with debugging too, if I can be of any help. I am
running Mandrake 8.1 though.

Comment 16 Robert J Birkett 2002-05-29 17:51:14 UTC
This problem has been around for a long time.  On IBM and Compaq laptops of 
varying types, USB support is not working, most likely because of a bug in the 
USB_OHCI drivers.  I have tried many different settings to resolve this issue 
but to no avail.  The most annoying piece of the puzzle is that all the 
hardware is correctly identified and the system ONLY locks up when loading the 
USB drivers of any type (ohci or other).  There is definitely a driver problem 
here that affects a huge number of machines using this specific chipset.  I'm 
almost at the point of buying a new laptop since this problem is unlikely to be 
resolved anytime soon.  I did manage to get RHL 7.3 installed afer a lot of 
searching since the nousb option does not work during install (oops!) and you 
have to disable pcmcia at startup to avoid consecutive lockups.  The i1300 
series has no serial port so it's USB or PS2 port only.  I wish this could be 

Comment 17 Need Real Name 2002-07-22 12:24:09 UTC
I had the same problem on a TP i1200 and this is only workaround I found. On
starting the install, type "linux pci=conf2" or "linux pci=off" as the
bootloader options. This will suppress the lockup on detection of USB devices on
the computers that have the defective USB. If you want to have the full text go to :


Hope this helps !

Comment 19 Pete Zaitcev 2002-10-04 17:49:22 UTC
The "nousb" option is fixed in RH8.0, so there's no need for gymnastics
with PCI detection.

This bug is stalled, basically. Someone has to poke IBM and ALi and
get specs and errata, but I really do not have the time.
