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.
