#172 ACER Aspire laptop hangs when launching pcmcia


I am installing Linux Mandrake 10.0 on an Acer laptop
Aspire 1350 (specifically 1356LMi).
I would like to use a Wi-Fi Cardbus Card from SMC (2835W).
The system freezes when trying to enable pcmcia support
(either at boot or in-session). The only way out is a
brutal reset.
This occurs whether a PC Card is in or not.
Actually it is enough to load yenta_socket to produce
the freeze.
There is nothing in syslog (perhaps because of the hard
reset ?).
I have tried with ACPI on/off and APIC on/off in all
combinations of both. No result.
I have tried in /etc/sysconfig/pcmcia to set
PCIC_OPTS="do_scan=0" and some "irq_list=..." (only a
few combinations, I must admit).No success.
I have also tried to exclude specific IRQs through
/etc/pcmcia/config.opts (those which were not listed as
already attributed in /proc/interrupts). No result.

[ Note : there is another problem, I don't know if it
is related or not ; USB 2 devices are not recognised
when ACPI is on, but are recognised when ACPI is off.
By not recognised, I mean there is no initial dialog
and nothing appears in /proc/scsi/scsi.In contrast,
USB 1.1 devices are recognised and automatically
mounted without difficulty whether ACPI is on or off.]

The kernel is 2.6.3-13mdk
The pcmcia driver is 3.2.5
The CardBus Controller is Texas Instruments PCI-1410
(it is correctly recognised by HardDrake which also
affects it
the yenta_socket driver).
The output of lspci concerning this device is as follows :
00:07.0 CardBus bridge: Texas Instruments PCI1410 PC
card Cardbus Controller (rev 02)
Subsystem: Acer Incorporated [ALI]: Unknown device 0033
Flags: bus master, medium devsel, latency 0, IRQ 5
Memory at 20000000 (32-bit, non-prefetchable) [size=4K]
Bus: primary=00, secondary=02, subordinate=05,
I/O window 0: 00000000-00000003
I/O window 1: 00000000-00000003
16-bit legacy interface ports at 0001

Can somebody suggest a solution ?

    I would recommend a kernel upgrade; PCMCIA in 2.6 kernels is
    somewhat unstable. If the problem persists, then report it
    on the linux-pcmcia mailing list, here:


    which is specifically for discussion of 2.6 kernel PCMCIA
    development. Since you have a problem even just inserting
    yenta_socket, the problem is not actually in the pcmcia-cs
