Description of problem:
Radeon IGP chipsets are having machine check exceptions happen
as soon as PCMCIA starts up. The reason for this is that its poking
the reserved areas (0x380-0x3ff) even though it shouldn't be, and is marked
clearly in the config.
Changing the include line from..
include port 0x100-0x4ff, port 0xc00-0xcff
include port 0x100-0x379, port 0x400-0x4ff, port 0xc00-0xcff
(Ie, doing the exclude by hand) confirms that this is the problem.
Additionally, the range is too wide. It should exclude 0x3b0 -> 0x3bb
and 0x3b3->0x3b3. This aparently is the reason why we are having problems with
Sony VAIO laptops & their CD drives.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. boot on RadeonIGP system
2. Start PCMCIA
Actual Results: Fatal MCE
Expected Results: Boots correctly.
<davej> should be 3d3
Dave, do we need to build a new kernel-pcmcia-cs?
I think Bill already did, though I've not confirmed this since.
I'll look into it.
Bug #104320 also says that a kernel-pcmcia-cs update will fix the bug, but there
hasn't been any update....
Confirmed, the exclude list is now being honoured with the default config
with the current pcmcia-cs package.
No more MCEs...
I still hang if the internal NIC is plugged in at boot-up, which Bug #104320
says is fixed by this exclude list
reopen? something else?
likely something else.
