Do you get anything at all in syslog after this? Or syslog is already stopped at this point? > /usr/lib/pm-utils/functions: line 89: log: command not found WTF??? This is a 2 year old bug in pm-utils. OpenSUSE 11.3 fixed that in 1.3.0. Please see if this fix gets rid of the "log" error: <http://lists.freedesktop.org/archives/pm-utils/2010-September/002219.html>. > Failed. > Unloading kernel module ehci_hcd... > ---- > > Now stuck at unloading ehci_hcd. > > I get the same behaviour trying to unload uhci_hcd or ehci_hcd after the > first successfull suspend and restore.

Perhaps someone more knowledgeable can tell whether this is kernel's or kmod's fault... Finally, have you actually tried to remove *_hcd from MODULE_SUSPEND and see if it works? -- Leonid Isaev GnuPG key: 0x164B5A6D Fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D
