*** DANGER *** unable to remove socket power

[John Baker]

Hi,

I'm having trouble with 2.6.14 and getting Linux to recognise my PCMCIA card. 
I've spotted this message in my kernel logs:

Dec 24 11:03:29 flygirl PCMCIA: socket c19d842c: *** DANGER *** unable to 
remove socket power

And having tried the reserve option in the kernel parameters, the problem 
refuses to go away:

  kernel (hd0,0)/boot/kernel-genkernel-x86-2.6.14-gentoo-r5 root=/dev/ram0 
init=/linuxrc ramdisk=8192 real_root=/dev/hda1 udev noapic nolapic 
noapictimer video=vesafb,mtrr ec_burst=1 reserve=0xc020a000,0x5000

(Although I must admit, looking at the debug information now, the reserve 
address seems to have changed since I last calculated it!).

Therefore, permit me to paste the relevant information in the hope someone can 
tell me if I've done something wrong:

3.3.6, ssp-3.3.6-1.0, pie-8.7.8)) #1 PREEMPT Sat Dec 24 10:31:58 GMT 2005

Any thoughts welcome!

Thanks and Merry Christmas.
