Description Scott Bowers 2007-06-06 12:16:17 UTC
System Info:
Fedora Core 6 PPC
Machintosh Powerbook G3 (Pismo)
Kernel 2.6.20.-1.2948.fc6 on a ppc

Upon insert of a DWL-650 wireless NIC or when booting the Mac with the card
inserted, the system will freeze.  The following error is printed onto the
command line:

pccard: PCMCIA card inserted into slot 0
Caused by (from SRR1=49030): Transfer error ack signal

Additionally, the following backtrace is dumped onto the screen:

  msr: 49030

I've also duplicated this problem with an Intel Pro/Wireless 2011 card

Comment 1 Chuck Ebbert 2007-06-06 18:57:11 UTC
According to:
http://lists.infradead.org/pipermail/linux-pcmcia/2006-April/003488.html

adding the kernel parameter:
    reserve=0xfd000000,0xffffff

should fix this. However other people report that with 2.6.20 that does not
work:

http://lists.infradead.org/pipermail/linux-pcmcia/2007-April/004500.html

Please try and report back.

Comment 2 Scott Bowers 2007-06-06 19:20:55 UTC
I have tried booting with the kernel parameter "reserve=0xfd000000,0xffffff" and
it has no affect on resolving the issue.

Additionally, prior to upgrading to 2.6.20, I had 2.6.18 installed.  I tried the
"reserve=0xfd000000,0xffffff" boot parameter with it and received the same
error.  The second link you offered suggests that this fix works with 2.6.17, so
that may be a clue that something was introduced in 2.6.18 that caused this issue.

Comment 3 Chuck Ebbert 2007-06-20 21:21:14 UTC
Try adding

  pcmcia_core.probe_mem=0

to the kernel command line.
