Hello all, For a long while now I've not been able to get suspend-to-ram to work on my HP Pavilion dv5200tx. Has anybody had any luck with this laptop model?
Symptom: Suspend happens fine. On resume, there is very little activity (which I think is just the system looking at the DVD-ROM drive on startup) and then nothing happens -- the system hangs. The problem is not that of the display not returning -- *nothing* works. I have to do a hard power-off. I've tried with s2ram -f -a {1|2|3} as well as -p -s (booting with init=/bin/bash and keeping the kernel relatively minimal). Suspend-to-disk works, mostly (it worked consistently on 2.6.20.something, IIRC, broke in between, and now seems to be back). I suspect the AHCI driver (I've tried ata_piix too, but that too hangs on resuming after an s2ram -f). I don't know if this is useful here, but when trying suspend2, I get the following message: <snip> PCI: Setting latency timer of device 0000:00:1f.2 to 64 scsi0 : ahci PM: Adding info for No Bus:host0 Device driver host0 lacks bus and class support for being resumed. scsi1 : ahci PM: Adding info for No Bus:host1 Device driver host1 lacks bus and class support for being resumed. scsi2 : ahci PM: Adding info for No Bus:host2 Device driver host2 lacks bus and class support for being resumed. scsi3 : ahci PM: Adding info for No Bus:host3 Device driver host3 lacks bus and class support for being resumed. ata1: SATA max UDMA/133 cmd 0xf882c500 ctl 0x00000000 bmdma 0x00000000 irq 219 </snip> Please let me know if there's more information that I can provide. Any help would be *greatly* appreciated.
