Hi, I inherited a computer which I want to make a sleeping backup computer. The idea is that it sleeps during the day and then I wake it with arp -W and it receives backups and then it goes back to sleep, but I'm running into problems.
First with a snapshot kernel when I wake the box I get this, and the system is inoperable (due to the ahci not coming ready, 3rd line from top, sorry about the flash on my camera, I had one shot and I didn't want to repeat the moment). The screenshot is here: http://centroid.eu/private/ahci-problem.jpg Then I added a longer timeout on ahci and it at least put the wake state into a stable state, here is my patch but it's far from perfect: Index: ahci.c =================================================================== RCS file: /cvs/src/sys/dev/ic/ahci.c,v retrieving revision 1.32 diff -u -p -u -r1.32 ahci.c --- ahci.c 21 Aug 2017 21:43:46 -0000 1.32 +++ ahci.c 9 Apr 2018 21:36:47 -0000 @@ -1504,7 +1504,7 @@ retry: /* Wait for device to become ready */ if (ahci_pwait_clr(ap, AHCI_PREG_TFD, AHCI_PREG_TFD_STS_BSY | - AHCI_PREG_TFD_STS_DRQ | AHCI_PREG_TFD_STS_ERR, 3)) { + AHCI_PREG_TFD_STS_DRQ | AHCI_PREG_TFD_STS_ERR, 10)) { /* even if the device doesn't wake up, check if there's * a port multiplier there */ It could be perfect, but there is still a problem. When I put the box back to sleep it goes shortly for a blip second and then it wakes again, almost like there is data in its wake buffer that was never flushed. I'm suspecting it's probably caused by the drm WARNINGS. At last under my signature I'm going to have the dmesg with 2 wake sessions. So I'm wondering if anyone has hints, patches to try, or otherwise?
