Description Forgotten User --EoyBps8f 2005-09-19 22:20:24 UTC

When I have my PCMCIA network-adapter plugged in when suspending to disk and 
try to restore without the adpater plugged in, the restoring fails after 
stating something like: 
All taks have been restored. 
CapsLock and ScrlLock blink periodically. 
 
If I have the adapter plugged in, it works perfectly. 
 
Maybe removeable devices should not be "saved" when suspending.

I solved the issue by using acpi=off, not sure if this works on PCs that do  
support ACPI though. I cannot test the latter as I do not own such a notebook.  
  
However this is another reason to make sure whether the notebook actually  
supports ACPI before enabling it by default! See bug 117820. 
 
If this works on a notebook that supports acpi with acpi=on, then this bug can 
be closed.

This is clearly one of the things you should not do, regardless of if you are
using ACPI or APM: modifying the hardware during suspend is asking for trouble.

You could use SUSPEND*EJECT_PCMCIA=yes in /etc/sysconfig/powersave/sleep to
eject the card before suspend to work around this problem.

I do not think so! Imagine you are working somewhere where you have to use  
battery. You get a call, do not watch the system, it stays idle for some time  
and goes into suspend-to-disk. You pack your stuff, which means that you  
remove removeable things like USB and PCMCIA and go home, you turn on you  
notebook and it hangs. 
 
 
If there is a removeable device, ACPI it should be  
handled as removeable and not as static.  
 
Obviously I agree that removing some non-removeable-devices is not a good  
idea, yet removing removeable devices is their actual sense, as the term  
already states. ;)

I know I can. Yet Joe Smith does not, because s/he does not know about it and
relies on the _removable_ in removable-device. Hence I think that
SUSPEND*EJECT_PCMCIA=yes should be default. If there is such a switch for USB,
it should also be switched to yes by default.

What disadvantages would it have, to set both of these to yes?

Comment 7 Forgotten User ZhJd0F0L3x 2005-09-21 08:44:25 UTC

USB is "unplugged" by removing the host controller modules already.
If you eject the PCMCIA card that holds your $HOME on an external drive, you
won't be lucky after resume. This is why it is not set to yes. Also, it usually
does not break. If it does, you have hardware with buggy drivers that should be
fixed.
