pata_it821x locks up the machine
Last modified: 2007-11-30 17:12:08 EST
Description of problem:
There is a PC with the ITE8212 raid controller,
to which the cd-rom is attached.
FC6 installed and worked without any problems
on this PC.
Trying to install F7 locks up the machine when
it is trying to load the pata_it821x driver.
We disabled the controller in bios setup to
install F7 anyway. Since the cdrom became disabled,
we booted from flash and did a network install.
After install, the problem didn't disappear.
The machine locks up on "Starting udev".
The only way to use F7 on this machine was to
add the pata_it821x to /etc/modprobe.d/blacklist
and live without a cdrom.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Get the PC with the ITE8212 raid controller first.
2. Start the F7 installation
3. See the machine locked up when trying to load the driver
F7 installation freezes on start; F7 freezes on startup.
F7 installs; F7 boots; F7 works
The noraid option doesn't make any difference.
Actually, loading the pata_821x itself doesn't
lock up the machine, but loading sr_mod after it -
does. Still I think the problem is in the it821x
driver, but this is just a guess.
I'll attach the lspci and dmesg outputs.
The dmesg output is from the unupdated F7 kernel,
but the update released to that time, does not
solve the problem.
