mine works fine here with a xircom ce2/3 and a ne2000

may be a problem with the assigned resources in config.opts. mine attached

i disagree. i haven't seen a single report with problems on topic97.
show me one and i change my mind. for revisions < 5.

also i'm not using 2.6.12 but the git tree from yesterday. this has
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12/2.6.12-mm1/broken-out/yenta-ti-turn-off-interrupts-during-card-power-on-more-2.patch
already applied. one of the effects is that it helps if the socket is
in a bad state after boot. please test with that one and see if those
	[busy], [bat dead], [bat low], [req attn]
go away.

for the interrupt storm your seeing: i cannot reproduce them. i tried
both cards using ISA and using the PCI interrupt. stable here.

also a full dmesg and a hexdump of /proc/bus/pci/xx/yy.z
of the cardbus bridge please. my bios may have done a bit
more than yours so a bit of more init code could be needed.

# Local PCMCIA Configuration File

#----------------------------------------------------------------------
#
# System resources available for PCMCIA cards
#
# NOTE: these settings have no effect on resources assigned to a
# CardBus bridge device itself; this file only affects resources
# assigned to cards.  Also, interrupt settings here will only affect
# ISA bus interrupts assigned to 16-bit cards.  PCI interrupts
# generally can't be reconfigured.
#
# With the kernel PCMCIA subsystem, these settings also have no effect
# at all on resources used for 32-bit CardBus cards.  Those are set by
# the PCI hotplug subsystem.
