Hello, I'm asking for help as I absolutely cannot resolve this issue. 1. I'm using RR Loader (v25.9.7) with SA6400 (DSM 7.2.2-72806 Update 4). 2. An error occurs when starting a VM in Virtual Machine Manager (v2.7.0-12229). 3. There were no issues when installing Virtual Machine Manager, and the same problem persists even after reinstallation. ... 2025-11-13T10:19:41+09:00 KEHRD kernel: [88079.066908] BUG: sleeping function called from invalid context at kernel/locking/rwsem.c:1556 ... 2025-11-13T10:19:42+09:00 KEHRD kernel: [88080.300145] BUG: scheduling while atomic: qemu-system-x86/20850/0x00000002 2025-11-13T10:19:42+09:00 KEHRD kernel: [88080.307166] Modules linked in: pci_stub vfio_pci vfio_virqfd vfio_iommu_type1 vfio vhost_net(O) tun kvm_amd kvm irqbypass nfnetlink xfrm_user xfrm_algo xt_ipvs ip_vs_rr ip_vs xt_mark iptable_mangle br_netfilter bridge stp aufs macvlan veth xt_addrtype xt_MASQUERADE xt_REDIRECT xt_nat vfat fat tcm_qla2xxx(O) qla2xxx(O) nvme_fc nvme_fabrics libfc scsi_transport_fc vhost_scsi(O) vhost(O) vhost_iotlb(O) tcm_loop(O) iscsi_target_mod(O) target_core_user(O) target_core_ep(O) target_core_multi_file(O) target_core_file(O) target_core_iblock(O) target_core_mod(O) syno_extent_pool(PO) rodsp_ep(O) udf isofs synoacl_vfs(O) btrfs raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq iptable_nat xt_conntrack xt_mac xt_geoip(O) compat_xtables(O) ip6table_filter ip6_tables xt_recent xt_iprange xt_limit xt_state xt_tcpudp xt_multiport xt_LOG iptable_filter ip_tables x_tables 8021q nfsd lockd grace rpcsec_gss_krb5 auth_rpcgss sunrpc hid_generic openvswitch nsh nf_nat gre usblp 2025-11-13T10:19:42+09:00 KEHRD kernel: [88080.307206] nf_conntrack lrw nf_defrag_ipv6 nf_defrag_ipv4 gf128mul epyc7002_synobios(O) dm_crypt essiv sg dm_snapshot dm_bufio crc_itu_t crc_ccitt psnap p8022 llc hfsplus md4 hmac sit tunnel4 ipv6 flashcache_syno(O) syno_flashcache_control(O) dm_mod zram zstd zstd_compress lzo_rle lzo aesni_intel glue_helper crypto_simd libarc4 cryptd ecb authenc des_generic libdes ansi_cprng cts md5 cbc cpufreq_powersave(OE) cpufreq_performance(OE) acpi_cpufreq vxlan ip6_udp_tunnel udp_tunnel ip_tunnel loop sha256_generic libsha256(OE) synorbd(O) synofsbd(O) sch_sfq(OE) sch_netem(OE) sch_multiq(OE) sch_mqprio(OE) sch_htb(OE) sch_fq_pie(OE) sch_pie(OE) sch_fq_codel(OE) sch_fq(OE) sch_codel(OE) sch_cake(OE) tcp_yeah(OE) tcp_westwood(OE) tcp_veno(OE) tcp_vegas(OE) tcp_scalable(OE) tcp_nv(OE) tcp_lp(OE) tcp_illinois(OE) tcp_hybla(OE) tcp_htcp(OE) tcp_highspeed(OE) tcp_dctcp(OE) tcp_cdg(OE) tcp_bic(OE) tcp_bbr(OE) virtiofs(OE) fuse(OE) virtio(OE) virtio_ring(OE) 9p(OE) 9pnet(OE) lm90(OE) lm78(OE) lm75(OE) 2025-11-13T10:19:43+09:00 KEHRD kernel: [88080.396081] adm9240(OE) regmap_i2c(OE) adm1031(OE) adm1021(OE) adt7475(OE) adt7470(OE) hwmon_vid(OE) pcspkr(OE) pcspeaker(OE) uas usbhid hid usb_storage pgdrv(O) r8169_lk(OE) realtek(OE) mdio_devres(OE) of_mdio(OE) fixed_phy(OE) libphy(OE) evdev(OE) rtc_cmos(OE) r8168_tx(OE) thermal(OE) button(OE) xhci_pci xhci_hcd uhci_hcd ehci_pci ehci_hcd usbcore usb_common [last unloaded: irqbypass] 2025-11-13T10:19:43+09:00 KEHRD kernel: [88080.520644] CPU: 5 PID: 20850 Comm: qemu-system-x86 Tainted: P W OE 5.10.55+ #72806 ... 2025-11-13T10:19:42+09:00 KEHRD kernel: [88079.656044] qemu-system-x86[20850]: segfault at 5576c6659308 ip 00007fe349176e09 sp 00007ffc28e67700 error 6 in libc.so.6[7fe349108000+14c000] 2025-11-13T10:19:42+09:00 KEHRD kernel: [88079.669105] Code: 8d 34 19 48 39 d5 48 89 75 60 0f 95 c2 48 29 d8 48 83 c1 10 0f b6 d2 48 83 c8 01 48 c1 e2 02 48 09 da 48 83 ca 01 48 89 51 f8 <48> 89 46 08 e9 7b ff ff ff 48 8d 0d 0b 93 0f 00 48 8d 15 c8 ec 0f 2025-11-13T10:19:42+09:00 KEHRD kernel: [88079.688237] BUG: scheduling while atomic: qemu-system-x86/20850/0x00000004 4. I thought the KVM module might be the issue, so I tried restarting it but the problem wasn't resolved. modprobe -r kvm_amd modprobe -r kvm modprobe kvm modprobe kvm_amd 5. I suspect it might be a virtual network adapter issue. ash-4.4# virsh net-list --all Name State Autostart Persistent ---------------------------------------------- default inactive yes yes 6. I've been trying to fix this problem for a month without any success.

2025年11月12 升级到7.3.1 版本出问题的临时解决方法： U盘如果是23.10 可以拔下来重启制作启动盘。新版本的是25.9.7 ip:7681 或者输入menu.sh 920+ 也是升级后出问题，进入设置菜单 > 选择编译引导，然后下载7.2 .pat > 重启后，用 Synology Assistant 搜索，按步骤还原修复成功

sa6400升级7.3.1后，启动失败，重新编译引导依然失联，等待rr更新中
