Ethernet connections break down, reading and writing from/to hd gives errors. The problem is reproducable with another hardware with same components and even with a different (sundance) 4-port ethernet card. For tests I simply copy a lot of files via NFS to the local hd. It always freezes the machine, not always ad-hoc, but within short. I checked with 2.4.19 - same problem. I can test patches on this, no production machine involved. Any hints appreciated. lspci -vv: 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 630 Host (rev 30) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- [disabled] Region 1: I/O ports at [disabled] Region 2: I/O ports at [disabled] Region 3: I/O ports at [disabled] Region 4: I/O ports at 4000 [disabled] [size=16] 00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 Control: I/O+ Mem+ BusMaster+ SpecCycle+ MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- [disabled] [size=128K] Capabilities: [40] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=160mA PME(D0+,D1+,D2+,D3hot+,D3cold+) Status: D0 PME-Enable+ DSel=0 DScale=0 PME- 00:02.0 PCI bridge: Silicon Integrated Systems [SiS] 5591/5592 AGP (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- Reset- FastB2B- 00:12.0 PCI bridge: Digital Equipment Corporation DECchip 21152 (rev 03) (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- Capabilities: [dc] Power Management version 1 Flags: PMEClk- DSI- D1- D2- AuxCurrent=220mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Bridge: PM- B3+ 00:13.0 PCI bridge: Digital Equipment Corporation DECchip 21152 (rev 03) (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- Capabilities: [dc] Power Management version 1 Flags: PMEClk- DSI- D1- D2- AuxCurrent=220mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Bridge: PM- B3+ 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] SiS630 GUI Accelerator+3D (rev 21) (prog-if 00 [VGA]) Subsystem: Silicon Integrated Systems [SiS] SiS630 GUI Accelerator+3D Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- 02:04.0 SCSI storage controller: Adaptec AIC-7892A U160/m (rev 02) Subsystem: Adaptec 29160 Ultra160 SCSI Controller Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- [disabled] [size=128K] Capabilities: [dc] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- 02:06.0 Network controller: Siemens Nixdorf AG DSCC4 WAN adapter (rev 21) 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- [disabled] [size=256K] 03:05.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41) Subsystem: D-Link System Inc: Unknown device 1132 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- [disabled] [size=256K] 03:06.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41) Subsystem: D-Link System Inc: Unknown device 1132 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- [disabled] [size=256K] 03:07.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41) Subsystem: D-Link System Inc: Unknown device 1132 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- [disabled] [size=256K] -- Regards, Stephan
