Hi! After a while I've updated my notebook. Formerly it was loaded with 2.6.15 and now it runs 2.6.18. All seems to be working well, except suspending, either to RAM or to disk. Both is blocked by very similar event. For example, the following is dumped when attempting to use STR: pnp: Device 00:09 disabled. Stopping tasks: ========================================================================| [ACPI Debug] String: [0x1B] "===== SST Sleeping S3 =====" Class driver suspend failed for cpu0 some devices failed to power down Could not power down device <4 random binary characters>: error -22 ACPI: PCI Interrupt 0000:00:02.7[C] -> Link [LNKF] -> GSI 10 (level, low) -> IRQ 10 PM: Writing back config space on device 0000:00:0c.0 at offset 1 (was 2100003, writing 2100007) ACPI: PCI Interrupt 0000:00:0c.0[A] -> Link [LNKC] -> GSI 5 (level, low) -> IRQ 5 pnp: Device 00:06 does not support activation. pnp: Failed to activate device 00:07. Restarting tasks... done [ACPI Debug] String: [0x1A] "===== SST Working S2 =====" [ACPI Debug] String: [0x17] "===== SST Working =====" Please look at thos 3 lines starting with "Class driver suspend failed for cpu0". On the 3rd, there are 4 non-ASCII characters as the name, which were unable to be transferred by mouse c&p (between text consoles). There are also another messages regarding device activation, which were not present in 2.6.15. Any help, how to get the system suspend working again, is highly appreciated.
