>Synopsis: ehci panic using a logic analyzer on ugen(4) >Category: <PR category (one line)> >Environment: System : OpenBSD 6.4 Details : OpenBSD 6.4-current (GENERIC.MP) #16: Sat Dec 15 09:36:44 -02 2018 dbolgher...@bike.home:/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64 Machine : amd64 >Description: When using a generic logic analyzer with comms/sigrok/sigrok-cli, most of the captures gives a panic and drop the system into DDB. The probability of a panic is higher when using higher samplerates as described below. >How-To-Repeat: Do a capture with something like this: $ sigrok-cli -d fx2lafw -o test.sr --time 10s -c samplerate=16m The panic is registered here: https://bolgh.com/ehci_panic.jpg Other notes: - To scan the device: $ sigrok-cli --scan The following devices were found: demo - Demo device with 12 channels: D0 D1 D2 D3 D4 D5 D6 D7 A0 A1 A2 A3 ftdi-la - FTDI FT232R USB UART with 8 channels: TXD RXD RTS# CTS# DTR# DSR# DCD# RI# fx2lafw:conn=1.3 - Saleae Logic with 8 channels: D0 D1 D2 D3 D4 D5 D6 D7 $ - Sometimes a libusb error is thrown (LIBUSB_ERROR_IO): $ sigrok-cli --scan sr: testo: Failed to get product string descriptor: LIBUSB_ERROR_IO. The following devices were found: demo - Demo device with 12 channels: D0 D1 D2 D3 D4 D5 D6 D7 A0 A1 A2 A3 ftdi-la - FTDI FT232R USB UART with 8 channels: TXD RXD RTS# CTS# DTR# DSR# DCD# RI# fx2lafw:conn=1.3 - Saleae Logic with 8 channels: D0 D1 D2 D3 D4 D5 D6 D7 $ >Fix: Don't know. dmesg: OpenBSD 6.4-current (GENERIC.MP) #16: Sat Dec 15 09:36:44 -02 2018 dbolgher...@bike.home:/sys/arch/amd64/compile/GENERIC.MP real mem = 8451125248 (8059MB) avail mem = 8185696256 (7806MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xdae9c000 (64 entries) bios0: vendor LENOVO version "8DET76WW (1.46 )" date 06/21/2018 bios0: LENOVO 4291MV7 acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SLIC SSDT SSDT SSDT HPET APIC MCFG ECDT ASF!
