2.6.22-rc3 hibernate(?) disables SMART on ide
I have 2 ide disks. If I enable SMART and hibernate/suspend2disk, SMART is disabled when I resume.

Use option -s with argument 'on' to enable it. According to the ATA standard, the device (drive) itself is responsible for preserving SMART enabled status over power cycles. It seems your drive doesn't wanna do that. I don't think mangling with SMART setup in the kernel is wise thing to do. Bruce, any ideas? Maybe hook smartd such that it gets suspend/resume events?

Maybe hook smartd > such that it gets suspend/resume events? 1) Enabling smart is a single command 2) The command should not fail, and if it fails, it's probably because it's not supported. There is nothing userspace can do better or worse. 3) There should be no bad effect from enabling smart, except if the BIOS insists on not booting because of a bad RAID disk. (That's why I like to disable it in the BIOS) 4) Not enabling smart is a common failure in many setups. Usurally the admin will have to enumerate the attached disks and patch the smartctl startup scripts. 5) Sometimes there is no smartd (or udev) running, and you'll still not want to re-enable smart each time you suspend. 6) A simple udev rule or smartd hook should be bigger than the code required in-kernel. Therefore I suggest setting the smart-enabled-bit in the kernel, in spite of not being the kernel's duty. It would be a 99,99% DTRT. OTOH: What would happen if the drive's command queue is full? What happens for DMA handling (can we hitch-hike)? Is it possible to just enqueue "enable_smart($DEV)"? -- Top 100 things you don't want the sysadmin to say: 48.

Maybe hook smartd > such that it gets suspend/resume events? Sorry, FYI, I made the same mistake as when I reported the wol problem - I was booting 2.6.21.1. I am having problems with 2.6.22-rc3 but when it does suspend/resume I can confirm that the problem is still there (of course). However your comments still stand. One unpleasant side effect is that I get hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hda: drive_cmd: error=0x04 { DriveStatusError } ide: failed opcode was: 0xb0 hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hda: drive_cmd: error=0x04 { DriveStatusError } ide: failed opcode was: 0xb0 ... and hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hdb: drive_cmd: error=0x04 { DriveStatusError } ide: failed opcode was: 0xb0 hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hdb: drive_cmd: error=0x04 { DriveStatusError } ide: failed opcode was: 0xb0 ... when the system comes back (induced from smartd I guess) until I do a: smartctl -son David - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

But I thought their PATA units might have kept that functionality. I have some modern seagate SATA drives here -- I'll try it on those too, just for my own education.
