In kernel 5.9.13 now don=E2=80=99t have any crashes in dimes but in one = moment accel service stop with defunct and in log have many of this line = : error: vlan608: ioctl(PPPIOCCONNECT): Transport endpoint is not = connected error: vlan617: ioctl(PPPIOCCONNECT): Transport endpoint is not = connected error: vlan679: ioctl(PPPIOCCONNECT): Transport endpoint is not = connected In one moment connected user bump double or triple and after that = service defunct and need wait to drop all session to start . I talk with accel-ppp team and they said this is kernel related problem = and to back to kernel 4.14 there is not this problem. Problem is come after kernel 4.15 > and not have solution to this = moment. Please help to find the problem. Last time in link I see is make changes in ppp_generic.c=20 ppp_lock(ppp); spin_lock_bh(&pch->downl); if (!pch->chan) { /* Don't connect unregistered channels */ spin_unlock_bh(&pch->downl); ppp_unlock(ppp); ret =3D -ENOTCONN; goto outl; } spin_unlock_bh(&pch->downl); But this fix only to don=E2=80=99t display error and freeze system=20 The problem is stay and is to big. Please help to fix.
