Am I right? Sorry if I was not clear in previous mail. suspend-to-ram and resume works fine if the machine doesn't mount internal emmc card to use it in way. If it boots from external mmc card or ssd disk attached over usb-c interface and use root filesystem (or any other filesystem, /home for example) on them (external mmc or disk on usb-c) it can go numerous times to suspend-resume cycles without any problem. But if any filesystem from emmc mounted then in can suspend and even resume, but when resumed after some random time it start to make problems: programs segfault, cant read or write files and similar issue. As I wrote in previous mail I can apply patches, build kernel and (maybe) tweak some parameters in kernel source (if I know which one should help me) to help subsystem developers to fix this problem. -- thanks > > > excerpt from dmesg output: > > > ----------------------------------------------------------------------- > > > Restarting tasks ... done. > > > PM: suspend exit > > > mmc_host mmc0: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) > > > mmc1: mmc_select_hs400es failed, error -110 > > > mmc1: error -110 doing runtime resume > > > mmc1: Got data interrupt 0x00000002 even though no data operation was in progress. > > > mmc1: sdhci: ============ SDHCI REGISTER DUMP =========== > > > mmc1: sdhci: Sys addr: 0x00000008 | Version: 0x00001002 > > > mmc1: sdhci: Blk size: 0x00007200 | Blk cnt: 0x00000008 > > > mmc1: sdhci: Argument: 0x00000000 | Trn mode: 0x00000023 > > > mmc1: sdhci: Present: 0x1fff0001 | Host ctl: 0x00000035 > > > mmc1: sdhci: Power: 0x0000000b | Blk gap: 0x00000080 > > > mmc1: sdhci: Wake-up: 0x00000000 | Clock: 0x0000bc07 > > > mmc1: sdhci: Timeout: 0x0000000d | Int stat: 0x00000000 > > > mmc1: sdhci: Int enab: 0x03ff000b | Sig enab: 0x03ff000b > > > mmc1: sdhci: ACmd stat: 0x00000000 | Slot int: 0x00000000 > > > mmc1: sdhci: Caps: 0x44edc880 | Caps_1: 0x801020f7 > > > mmc1: sdhci: Cmd: 0x00000c1a | Max curr: 0x00000000 > > > mmc1: sdhci: Resp[0]: 0x00000000 | Resp[1]: 0x373300bd > > > mmc1: sdhci: Resp[2]: 0x35303030 | Resp[3]: 0x00000000 > > > mmc1: sdhci: Host ctl2: 0x00000000 > > > mmc1: sdhci: ADMA Err: 0x00000000 | ADMA Ptr: 0xed41e200 > > > ----------------------------------------------------------------------- > > > > > > I invoke suspend-to-ram by `echo mem > /sys/power/state` from ACPI power > > > and LID button handlers. > > > > > > This only happens when I boot and use internal emmc card and never when > > > boot and use external mmc card. > > > > > > If suspend-to-ram is not invoked (machine is always in normal state) > > > this problem never happen (or I missed it somehow). > > > > > > I'm attaching kernel .config (file config-5.6.0-rc3-1-gru.conf) which > > > use to build kernel, output of the `awk -f scripts/ver_linux` as file > > > ver_linux.txt and output of dmesg as file mmc-err.txt (from which I > > > deleted wifi connection logs). > > > > > > Sorry if I did something bad or wrong with this bug report, I don't have > > > much experience with bug reporting, especially for kernel. > > > > > > I'm ready to send you more data, and investigate this more, apply > > > patches and rebuild kernel or whatever you ask me (of course if my > > > understanding and knowledge is enough for this job). > > > > > > Thank in advance > > > > > > -- > > > Kind regards > > > > > [...] > > > > > >
