https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243992 Vasile Buruiana <bvasea@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bvasea@gmail.com --- Comment #21 from Vasile Buruiana <bvasea@gmail.com> --- I found a way to re-create the problem: ######## how to become happy with your FreeBSD ########### Boot *win, make sure WiFi is working through Intel AC9560 Wireless adapter. Shut it down (start-shutdown) [OPTIONALLY: remove power cable from PSU, cou= nt 10 seconds, insert power cable]. Turn on the system. If FreeBSD is on anoth= er hard drive, enter your favorite mainboard firmware interface (BIOS/UEFI), change primary boot device to FreeBSD hard drive, save and exit. Boot Free= BSD. Surprise - iwm0 is loading: iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0xb4518000-0xb451bfff at de= vice 20.3 on pci0 iwm0: hw rev 0x310, fw ver 34.3125811985.0, address 28:7f:cf:f1:47:71 kldstat says: 41 1 0xffffffff84ff1000 16c20 if_iwm.ko 42 1 0xffffffff85008000 28df7f iwm9000fw.ko dhclient works fine. However the data rate is around 3 MBytes/second - mean= ing it transfers around 2 x 8", 1.2MB ancient floppy disks every single second,= or the same speed as a SCSI 1.2" 9-track open reel-to-reel tape drive. Anyway, better than the situation described below. ######## how to become sad ############ Boot *win, test your wifi connection. RESTART it (no shut down). If FreeBSD is on another hard drive, enter BIOS/UEFI, change boot device to FreeBSD, save and exit. Boot FreeBSD. Surprise: iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0xea238000-0xea23bfff at de= vice 20.3 on pci0 iwm0: fw chunk addr 0x404000 len 712 failed to load iwm0: iwm_pcie_load_section: Could not load the [0] uCode section iwm0: iwm_start_fw: failed 60 iwm0: Failed to start INIT ucode: 60 ############################################## # read from the beginning to be happy again # ##############################################=20 This should be something related to the firmware memory area not being rele= ased properly under *win when restarting, but properly released when *win is shutting down. FreeBSD is unable to transfer the uCode because AC9560 does = not accept - there is already a firmware loaded inside.=20 Please recreate this experiment to confirm. --=20 You are receiving this mail because: You are the assignee for the bug.
