Subject: PROBLEM: 8139too with MMIO hangs the system
Hi:
Whenever 8139too is loaded via modprobe, the entire system hangs.
If we compile the kernel with CONFIG_8139TOO_PIO=y, the problem
goes away. However, since every distro we've tried does not
compile the module this way, all of the installation CDs hang.
We were able to find a specially built Ubuntu that gets around
this. Magic Sysreq keys do not work when the system hangs in
this way.
We have reproduced this problem on the stock 2.6.20 Ubuntu
kernels, mainline 2.6.22, and 2.6.23-rc[12], plus all the
kernels that were running in the various installation CDs
we tried.
We set RTL8139_DEBUG to 3 in order to enable copious debug
info for this module in the 2.6.23-rc2 kernel. After doing
that, we get this in syslog when the laptop hangs:
ACPI: PCI interrupt for device 0000:03:04.0 disabled
we've tried booting with various options, including:
acpi=off
pci=noacpi
pci=nobios
pci=bios
pci=usepirqmask
pci=noirq
This is an Everex StepNote2053T Laptop. Our experience is described
here: http://www.poplarware.com/everexlinux.html
Ubuntu Laptop Testing page here:
https://wiki.ubuntu.com/LaptopTestingTeam/EverexStepNoteSA2053T
kernel config can be found here:
http://www.zachcarter.com/2.6.23-rc2-everex-8139too.config
Any help getting this fixed would be appreciated. We would be happy
to try any patches, or run any debug commands. It is rather
frustrating that none of the distros work out of the box on this
laptop, and would love to help prevent others from having this
same experience.
thanks!
