https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D280037 --- Comment #12 from ss3bsd <3226388001@jcom.home.ne.jp> --- > I'm now running the same machine with=20 > kern.ipc.tls.cbc_enable=3D0=20 > to see if the stability changes. The machine worked for 2 weeks without panic. Changed back kern.ipc.tls.cbc_enable=3D0 -> 1, a couple of days ago. The machine today panics again at CBC related part of code (ktls_ocf_tls_cbc_decrypt). So, the cause might be something specific to CBC. (not a strong evidence though.) -- Unread portion of the kernel message buffer: trap number =3D 12 panic: page fault cpuid =3D 1 time =3D 1721297633 KDB: stack backtrace: #0 0xffffffff809d2b5d at kdb_backtrace+0x5d #1 0xffffffff809858c1 at vpanic+0x131 #2 0xffffffff80985783 at panic+0x43 #3 0xffffffff80e5f91b at trap_fatal+0x40b #4 0xffffffff80e5f966 at trap_pfault+0x46 #5 0xffffffff80e36288 at calltrap+0x8 #6 0xffffffff80e21cc8 at bounce_bus_dmamap_load_buffer+0x178 #7 0xffffffff809c8a07 at bus_dmamap_load_crp_buffer+0x237 #8 0xffffffff82ddb7ad at qat_ocf_process+0x40d #9 0xffffffff80c83fd0 at crypto_dispatch+0x60 #10 0xffffffff80c8c3cd at ktls_ocf_dispatch+0x5d #11 0xffffffff80c8d3f4 at ktls_ocf_tls_cbc_decrypt+0x344 #12 0xffffffff80a1a484 at ktls_work_thread+0x664 #13 0xffffffff8093fc7f at fork_exit+0x7f #14 0xffffffff80e372ee at fork_trampoline+0xe Uptime: 2d17h13m52s --=20 You are receiving this mail because: You are the assignee for the bug.=
