Dear Maintainer, I am experiencing an issue where my system completely locks up when attempting a large network file transfer from a mounted smb share. When copying a file above 1 GB I am consistienly experiencing this behavior. I tried going back to the 6.12.3 kernel which is the oldest I have on the system and the probelm is there as well. Looking at the dump below my guess is that it was introduced with 6.12 and netfs/read_collect.c. I have been unable to get a dump with 6.12.15, but the behavior is consistient. The transfer starts, but after a few seconds the whole system locks up. 2/22/25 8:38 AM ------------[ cut here ]------------ 2/22/25 8:38 AM WARNING CPU: 4 PID: 291 at fs/netfs/read_collect.c:110 netfs_consume_read_data.isra.0+0x67f/0xb50 [netfs] 2/22/25 8:38 AM Modules linked in ccm nls_utf8 cifs cifs_arc4 nls_ucs2_utils cifs_md4 dns_resolver netfs snd_seq_dummy snd_hrtimer snd_seq snd_seq_device xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp nft_compat nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables bridge stp llc rfcomm cmac algif_hash algif_skcipher af_alg overlay qrtr bnep amd_atl intel_rapl_msr intel_rapl_common sunrpc edac_mce_amd binfmt_misc kvm_amd snd_hda_codec_realtek snd_hda_codec_generic snd_hda_scodec_component kvm snd_hda_codec_hdmi nls_ascii crct10dif_pclmul nls_cp437 snd_hda_intel crc32_pclmul ghash_clmulni_intel snd_intel_dspcfg btusb snd_intel_sdw_acpi sha512_ssse3 vfat fat snd_hda_codec sha256_ssse3 btrtl sha1_ssse3 btintel snd_hda_core aesni_intel btbcm ahci btmtk snd_hwdep gf128mul r8169 crypto_simd libahci snd_pcm bluetooth cryptd realtek snd_timer libata rapl sp5100_tco snd watchdog wmi_bmof mdio_devres gigabyte_wmi soundcore i2c_piix4 pcspkr i2c_smbus rfkill libphy scsi_mod ccp k10temp 2/22/25 8:38 AM scsi_common button lm92 msr dm_mod parport_pc ppdev lp parport efi_pstore configfs nfnetlink ip_tables x_tables autofs4 ext4 mbcache jbd2 razerkbd(OE) efivarfs raid10 raid456 libcrc32c crc32c_generic async_raid6_recov async_memcpy async_pq async_xor xor async_tx raid6_pq raid1 raid0 md_mod evdev joydev razermouse(OE) hid_generic usbhid hid amdgpu video amdxcp i2c_algo_bit drm_ttm_helper ttm drm_exec gpu_sched drm_suballoc_helper drm_buddy drm_display_helper xhci_pci xhci_hcd drm_kms_helper drm nvme usbcore cec rc_core nvme_core crc32c_intel crc16 usb_common wmi gpio_amdpt gpio_generic 2/22/25 8:38 AM CPU 4 UID: 0 PID: 291 Comm: kworker/4:2 Tainted: G OE 6.12.3-amd64 #1 Debian 6.12.3-1 2/22/25 8:38 AM Tainted [O]=OOT_MODULE, [E]=UNSIGNED_MODULE 2/22/25 8:38 AM Hardware name Gigabyte Technology Co., Ltd.
