Subject2.6.13-rc4: yenta_socket and swsusp
[now sending to lkml as sending to the pcmcia list without being
subscribed seems to go to /dev/null]

I do have problems with yenta_socket on my x86_64 laptop which appear
when using swsusp (suspend to disk mode).

1. When I do not access any pcmcia device from initrd during boot
I have to terminate cardmgr, otherwise suspend to disk hangs.
For 2.6.11 it was sufficient to call 'cardctl eject'.

2. When I have to access a pcmcia device from initrd during boot
(there's required crypto keys stored on a pcmcia flash disk)
and I do not unload yenta_socket prior to suspend the laptop
spontaneously reboots or just hangs on resume when swsusp has
finished loading.

3. If I do not unload the pcmcia modules prior to suspend with
rmmod -w unloading yenta_socket fails.

4. If I do unload the pcmcia modules in a loop with rmmod -w
but no delay between unloading the modules it happens from
time to time that yenta_socket unloading hangs with a use
count of 2 when there is definitely no more user of the module.
A delay of 50 msec after unload of each pcmcia module seems
to cure this.

5. If I insert yenta_socket within the first few seconds after resume
the laptop spontaneously reboots. A 5 second delay seems to cure
this most of the time.

BTW:
Did I read this right? PCMCIA control ioctl (needed for pcmcia-cs
[cardmgr, cardctl]) scheduled for removal in november *this* year? So a
3 month warning for everybody is sufficient? Probably only one kernel
release? So much for sufficient backwards compatability. Especially as
the tools stated to be required aren't even released as of today (hint:
module-init-tools 3.2). Grrr.
