Subject: Bug Report 2.4.20: Interrupt sharing bogus
Date: Wed, 11 Dec 2002 19:55:01 +0100 [thread overview]
Message-ID: <20021211195501.7f6dff35.skraw@ithnet.com> (raw)
Hello all,
It took me several days to find out this pretty simple sounding problem:
I have a stock 2.4.20 on a PIII-box with SIS chipset (lspci below), adaptec
U160-type controller and tulip-based 4-port ethernet card.
_If_ I use an ethernet port with same irq like adaptec controller, the system
goes instable and both components go crazy. 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.
