Subject: acpi breaks async interface
Date: Tue, 6 Feb 2001 00:46:42 +0100 [thread overview]
Message-ID: <20010206004642.A24599@rak.isternet.sk> (raw)
Hello,
I just found a strange thing in 2.4.1 (don't know, if the same
occured in 2.4.0) and 2.4.1-ac3. When I enable ACPI, my serial
port starts to drop some characters. When making ppp over this
and doing ping, it causes great packet losts. If I turn ACPI in
this configuration off, it works with no problems. I tried to
switch serial port IRQ to other one (was 4, switched to 3 and
tested) and it didn't help. Maybe something's broken.
