SubjectKernel 2.4.17 with VT8367 [KT266] crashes on heavy ide load togeter with heavy network load
Date
Hi !

I have problems with PC mainboard using the Via VT8367 [KT266] chipset.
lspci shows the configuration:
lspci
00:00.0 Host bridge: VIA Technologies, Inc. VT8367 [KT266]
00:01.0 PCI bridge: VIA Technologies, Inc. VT8367 [KT266 AGP]
00:0c.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139 (rev 10)
00:0e.0 Unknown mass storage controller: Promise Technology, Inc. 20268 (rev
01)00:0f.0 Unknown mass storage controller: Promise Technology, Inc. 20268
(rev 01)00:11.0 ISA bridge: VIA Technologies, Inc. VT8233 PCI to ISA Bridge
00:11.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06)
01:00.0 VGA compatible controller: ATI Technologies Inc Rage XL AGP (rev 27)

The CPU is a 1400MHz Athlon.
We use this system for a software Raid 5. If we produce heavy load on the
disks and network the system hangs. There is no log of errors at all. We
tried to change the network card form a 3com to a rtl83xx. The system remains
a litle longer stable but crashes then too. We also tried to have the
harddisks on seperate ide channels but this didn't solve the crashs.
It seems to be something with the dma, because if we disable the dma of the
harddisks the system is stable. Does anybody also recognise this problem ?
Is there any solution for this effect ?

Thanks a lot

Kai
