I have Gigabyte 965P-DS4 with ICH8R and additional JMicron 363 for IDE support. In 2.6.19-gentoo-r4 suspending worked fine. In 2.6.20 I'm getting next messages in dmesg: ata9: suspend failed, device 0 still active pci_device_suspend(): ata_pci_device_suspend+0x0/0x50() returns -16 suspend_device(): pci_device_suspend+0x0/0x80() returns -16 Could not suspend device 0000:04:00.1: error -16 and echo disk >/sys/power/state fails with write error lspci output: 04:00.0 SATA controller: JMicron Technologies, Inc.

I'd tried to remove recent pata_jmicron and quirks patch that was introduced in 2.6.20 compared to 2.6.19, but this didn't helped
Did you use pata_jmicron under 2.6.19?

same error message #echo standby >/sys/power/state bash: echo: write error: Resource temporarily unavailable # cat /sys/power/state standby

GNUtoo, open a new bug Max, please reproduce with 2.6.21-rc1
(In reply to comment #6) > Max, please reproduce with 2.6.21-rc1 With pata_jmicron loaded situation is the same, but with unloaded module it is even worse - it is just can't be suspended and after switching off the screen, and the lan, it is waiting for watchdog reboot or AltSysRQ. btw, 2.6.20 when going to suspend don't turned off the lan so i can see link light on my router, and when I push power on button on the case than the system starts than turning off itself and never going POST OK. To boot it in resume mode or any i needed to turn off power switch until disappearing of the link signal from that sysem on the router, but after resume the network is very unstable, some packets is silently dropping e.t.c; normal rebooting fixes that. So there may be second problem with net hardware because in 2.6.21-rc1 I see that the lan has switched off, but after that system doesn't go to poweroff state.
Any chance you can reproduce on 2.6.21-rc5? Suspend issues should be mostly fixed now so hopefully you can at least suspend without pata_jmicron...

OK, i'm marking this as fixed because the libata pata drivers are still experimental. You should open new bugs for your 2.6.21-rc5 issues at http://bugzilla.kernel.org. The idea of -rc releases is that bugs get fixed before it goes final.
