Comment 31 for bug 559163

Thank you soren121 - the HAL replacement was what I was thinking of but couldn't remember. Talking about hardware got me curious, so I pulled out a Dell docking station (D/APR PR01X) and suspended the laptop. So far suspend/resume almost always fails when the laptop is on its own, but when the laptop is docked, suspend/resume works perfectly!

Did some more digging. When the D600 is docked, not only is there a difference in the listed modules in /var/log/pm-suspend.log (to be expected?), but there is also a change in the order in which they are listed (see attached). Specifically:

Module Size Used by
nls_iso8859_1 3249 0
nls_cp437 4919 0
vfat 8901 0
fat 47767 1 vfat

As far as I can tell, these four modules appear only when the D600 is UNDOCKED and does NOT suspend/resume successfully. There may be other differences as well. Might try blacklisting them and see what happens.

Again, apologies if something is unclear or I'm not providing enough specific info.
