Created attachment 275019 [details] pciebus error crash liveusb fedora27 hard disk removed, usb flashdrive Several times a day my new build freezes, usually after 1 hour but after it happened the first time it is more frequent. I always keep a terminal open with journalctl -f and before the crash I start seeing errors on PCIe bus Mar 30 11:12:57 localhost-live kernel: pcieport 0000:00:01.2: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=000a(Transmitter ID) Mar 30 11:12:57 localhost-live kernel: pcieport 0000:00:01.2: device [1022:15d3] error status/mask=00001000/00006000 Not just Data Link Layer errors. [liveuser@localhost-live ~]$ lspci -d 1022:15d3 00:01.2 PCI bridge: Advanced Micro Devices, Inc. [AMD] Device 15d3 00:01.6 PCI bridge: Advanced Micro Devices, Inc. [AMD] Device 15d3 After a maximum of 3 minutes from those messages the mouse stop responding, the keyboard keep working, the network became unavailable, then the hard disk get stuck and is expelled and after that I only see pciebus error on tty2 or it freeze completely. At that point I try to reboot with a sysqr or I shut down the machine. The log I have attached are from a Fedora 27 live (kernel 4.13.9) booted via usb through my phone (usb mountr - usb gadget) because otherwise the hard disk became unavailable and it was impossible to save the log. I have removed the hard drive and cdrom drive, I don't have any pciexpress card in the slot. During the log I had a usb flash drive that also became unavailable. I was able to save the log opening my phone in nautilus using mtp://. The same happens with Ubuntu 18.04 with 4.15 and also 4.16rc7 kernel when I attach the hard drive. In that case I see hidden between the pcieport errors also 1 or 2 sata hard reset and ata failed check power mode. I have cleared the CMOS and removed the bios battery but it still happens, I have also tried to set "Typical current Idle" in the bios since I bought a PSU not zero load certified because I didn't know it. if I boot with pcie_aspm=off the error disappears but it still freezes, pci=noaer same thing, pci=nommconf same thing, with pci=nomsi I can't boot. I've tried memtest and mprime and it doesn't seem to have problems and with high load it seems stable, one time it crashed after I stopped mprime. I have read many similar bug report and tried many suggestion but I seems to have multiple problems. I can't reproduce the problem, sometimes it is fine when I leave the computer idle. I don't have another PSU or another motherboard, it could be an hardware problem, I'll try to install Windows in the next days to see if it works stable there. The log are full of pcieport error, there are other kind of errors though, I have tried filtering them with grep -v pcieport and I can see this other errors: Mar 30 11:15:08 localhost-live kernel: ------------[ cut here ]------------ Mar 30 11:15:08 localhost-live kernel: WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:316 dev_watchdog+0x214/0x220 Mar 30 11:15:08 localhost-live kernel: Modules linked in: vfat fat fuse nf_conntrack_netbios_ns nf_conntrack_broadcast xt_CT ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_conntrack ip_set nfnetlink ebtable_nat ebtable_broute bridge ip6table_nat nf_conntrack_ipv6 nf_defrag_ipv6 nf_nat_ipv6 ip6table_mangle ip6table_raw ip6table_security iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack libcrc32c iptable_mangle iptable_raw iptable_security ebtable_filter ebtables ip6table_filter ip6_tables snd_hda_codec_realtek snd_hda_codec_generic amdgpu snd_hda_codec_hdmi snd_hda_intel snd_hda_codec snd_hda_core edac_mce_amd snd_hwdep snd_seq kvm_amd i2c_algo_bit joydev kvm ttm snd_seq_device drm_kms_helper snd_pcm drm snd_timer irqbypass snd wmi_bmof soundcore tpm_tis tpm_tis_core tpm sp5100_tco wmi video i2c_piix4 Mar 30 11:15:08 localhost-live kernel: shpchp acpi_cpufreq nls_utf8 isofs squashfs crct10dif_pclmul crc32_pclmul crc32c_intel 8021q ghash_clmulni_intel garp mrp stp llc uas r8169 mii usb_storage sunrpc scsi_transport_iscsi loop Mar 30 11:15:08 localhost-live kernel: CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 4.13.9-300.fc27.x86_64 #1 Mar 30 11:15:08 localhost-live kernel: Hardware name: To Be Filled By O.E.M.

Created attachment 275031 [details] Same crash log with ubuntu 4.15 and firmware downgraded I have tried downgrading the firmware to 4.50(the only other firmware compatible with my CPU) and now the problem seems less aggressive. It still freezes the computer but after I see the AER pcie bus errors I have more time to save the log or continue using the computer. I have attached the log of 3 different instances of the problem, in the file named "lot of errors before it freezes" at the last line of the log I was switching to TTY2 and I noticed in GDM that there was a popup with "no activity system is going to suspend soon", I had already disabled the suspension so it should not have said that. In the control center I still had the screen suspension enabled, but when the problem occurs I'm using the computer but now I disabled that too. Would it be possible that the trigger is a user space daemon? mar 31 17:34:20 ghv systemd[1]: Starting Daemon for power management.. mar 31 17:34:20 ghv dbus-daemon[1690]: [system] Successfully activated service 'org.freedesktop.UPower' mar 31 17:34:05 ghv thermald[1788]: NO RAPL sysfs present mar 31 17:34:05 ghv thermald[1788]: Unsupported cpu model, use thermal-conf.xml file or run with --ignore-cpuid-check mar 31 17:34:05 ghv thermald[1788]: THD engine start failed
RMA'd the motherboard, sorry it was probably a hardware defect.
