Hello All,
I am using Kernel 6.6.47 and sometimes I see this in kernel logs:
[ 355.728634] mcp251xfd spi0.0 canfd0: IRQ handler mcp251xfd_handle_tefif() returned -22.
[ 355.728672] mcp251xfd spi0.0 canfd0: IRQ handler returned -22 (intf=0xbf1a0016).
After that the complete CAN is down.
ifconfig canfd0 down and up fixes the problem.
We are using two CANs (both mcp251xfd) at the same time in canfd mode.
We are sending about 9 Frames each 10ms on both CANs (bus load of about 35% per CAN).
Top shows about 10% of CPU Load on the SPIs:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5620 root -51 0 0 0 0 S 11.9 0.0 0:45.33 irq/45-spi0.0
Anyone an idea on this?
Regards,
Sven
