Hi Pavel,
there's some problems with swsusp in 2.6.12-rc3 (x86_64):

1. Is it necessary to print the following message during regular boot?
swsusp: Suspend partition has wrong signature?
It is a bit annoying and I believe it will confuse some swsusp
users.

2. PCMCIA related hangs during swsusp.
swsusp hangs after freeing memory when either cardmgr is running
or pcmcia cards are *physically* inserted. It is insufficient
to do a 'cardctl eject' the cards must be removed, too, for
swsusp not to hang. I do suspect some problem with the
'pccardd' kernel threads.

3. Sometimes during the search for the suspend hang reason the system
went during suspend into a lightshow of:
eth0: Too much work at interrupt!
and some line that ends in:
release_console_sem+0x13d/0x1c0)
The start of the line is not readable as it just flickers by in
the eth0 message limbo. NIC is a built in RTL-8169 Gigabit Ethernet
(rev 10). Oh, no chance for a serial console capture as there's no
built in serial device in this laptop.
