Description Ricky Ng-Adam 2004-03-14 12:55:40 UTC

Distribution: Mandrake 10 (b2, rc1, CE), Fedora2-test1
Hardware Environment: IBM Thinkpad A22m and Fedora2-test1
Software Environment: 2.6.1-2.6.3
Problem Description: Won't boot, hang at PCI

Steps to reproduce:

Full details: http://qa.mandrakesoft.com/show_bug.cgi?id=7947

Basically, it seems to hang here:

Serial: 8250/16550 driver $Revision 1.90$ 8 ports, IRQ sharing enabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
PCI: Found IRQ11 for device 0000:00:03.1
PCI: Sharing IRQ 11 with device 0000:00:03.0

The PCI device where it hangs seems to be the Intel PRO/100 SP Mobile Combo
adapter. I've tried MANY things to get it to boot (kernel options), with no
success and not only that but any other recent distro I try now seem to have
problems.

A very strange phenomenon: after an unsuccessful boot, if I poweroff the
computer, it will poweron by itself less then an hour later!! I would say HW
problem, but W2K works fine on this one and memtest gave out nothing.

Finally tried something I should have done long ago... I opened the back panel
of the laptop and carefully removed the network card board.

With the NIC removed, everything boots fine now, no problem! If I put it back,
it gets stuck at the same place So I can confirm that the problem is related to
kernel 2.6 and the Intel PRO/100 SP Mobile Combo Adapter (P/N 06P3819).  I doubt
the NIC itself is defective because it works in W2K.  

Still no clue what happenned in 2.6 that it would do this.

Is it a pcmcia/cardbus adapter?

Comment 3 Ricky Ng-Adam 2004-07-07 21:43:45 UTC

There is a PCMCIA/CardBus in that laptop:

  CardBus bridge: Texas Instruments PCI1450

But the NIC itself in inside the computer and I think it is directly connected
to the PCI bus.  I don't have anything in my PCMCIA slot.

Comment 4 Zwane Mwaikambo 2004-07-08 06:23:30 UTC

Ok so it's a mini PCI adapter, at this point, do you have any kernel which 
will boot on that system? If so which?

Can you reproduce
