I can confirm it for at least since 2.6.12. My current System is Ubuntu Dapper Drake. Whenever I copy a reasonably large file (> 150 MB) from my box to a WinXp SP2 box my system first gets very large latencies going up to 5 seconds. After nearly a minute of copying it will freeze completely. No Numlock no SysRq working anymore. No output in dmesg at all. It just starts getting slower with high latencies and will freeze completely if you not kill -9 the cp process. This so far has only happened to me on outbound copying. (E.g. cp a local file to remote) host. Inbound (WinXP to my Linux box) works flawlessly. Some more Info: cp process hangs with status D in wchan SendRe... kill -9 not working unless you delete the file on the remote site. Then cp exits as it should Mounting a CIFS fs from a WinXP SP2 box //xxx/DriveD on /mnt/xxx/D type cifs (rw,mand,noexec,nosuid,nodev) 10 Mbit lan 3Com Corporation 3c905B 100BaseTX System Info: uname -a Linux ubuntu 2.6.15-15-686 #1 SMP PREEMPT Thu Feb 9 20:19:53 UTC 2006 i686 GNU/Linux lspci -vvv 0000:00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 02) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- 0000:00:01.0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 02) (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap- 66MHz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- Reset- FastB2B+ 0000:00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02) Control: I/O+ Mem+ BusMaster+ SpecCycle+ MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR- 0000:00:12.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) Subsystem: 3Com Corporation 3C905B Fast Etherlink XL 10/100 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- 0000:00:14.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 06) Subsystem: Ensoniq Creative Sound Blaster AudioPCI64V, AudioPCI128 Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- SERR- fgrep -i CIFS /boot/config-2.6.15-15-686 CONFIG_CIFS=m # CONFIG_CIFS_STATS is not set # CONFIG_CIFS_XATTR is not set # CONFIG_CIFS_EXPERIMENTAL is not set -Christian - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
