Hi,
I am seeing the following error:
peak_pciefd 0000:06:00.0 can1: can_put_echo_skb: BUG! echo_skb is occupied!
I am running 4.13.10-rt3 kernel using the following PCIe card connect
to my board:
06:00.0 Network controller: PEAK-System Technik GmbH Device 0013 (rev 01)
Subsystem: PEAK-System Technik GmbH Device 0014
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 16
Region 0: Memory at fb100000 (32-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel driver in use: peak_pciefd
This occurs when I am sending messages over the CAN bus with
and without the other device on the bus also sending.
I have not seen this issue with other can devices in similar setups
(different kernel versions). It also only seems to occur on CAN1 which is
set to a higher baud rate then all the other buses.
I do have CONFIG PREEMPT RT turned on which might be exposing this
issue more often.
Has anyone seen this before? Does anyone know how to fix this or have a fix?
Thanks,
Diana Burgess
