Subject: BUG: iproute2 4.14.1 tc class add come to kernel-panic
Date: Mon, 29 Jan 2018 15:51:19 +0100	[thread overview]
Message-ID: <9AD3E60C0FF644D9B0EB7D279E3FE8CC@ROLANDAMD64> (raw)

Starting with Kernel 4.14.1 (x86_64) I found the following problem:
When I made the following commands:

tc qdisc add dev eth0 root handle 20: htb default 4 r2q 1
tc class add dev eth0 parent 20: classid 20:7 htb rate 10000kbit
tc qdisc add dev eth0 parent 20:7 sfq perturb 10
tc class add dev eth0 parent 20:7 classid 20:1 htb rate 200kbit ceil 
10000kbit prio 0

I become an Kernel-panic with the following output:
kern.err kernel: BUG: scheduling while atomic: tc/1036/0x00000200

The identical message come, when i try the kernel till 4.14.15.

When i have tested the same with one of the kernels from the 4.13 series,
i had no problem.Will this be solved in the kernel-series 4.14 or will this 
only with the
coming series 4.15 be made?

Kernel 4.15 is not be tested till now.

Best regards,
Roland Franke
