Subject: Re: PANIC , ide related (was lost interrupt hell)
Date: Thu, 09 May 2002 22:20:35 +0100 [thread overview]
Message-ID: <3CDAE823.5070304@notnowlewis.co.uk> (raw)

Upgrading to 2.4.19-pre8 has fixed the below oops, however, the lost
intrrupt problem is still there.
Details as follows :
Drives affected : Creative 5x DVD and LG CD-RW (in any
slave/master/channel config)
I have replaced the ide cables, disabled/enabled dma, used the via82xxxx
support, used the generic pci ide support, unmasked/masked the
interrupt, in all possible combinations. There are no irq conflicts.
The drives work perfectly in windows.
Replicating the trouble : try to rip any audio track from a cd using
cdparanoia, cdda2wav, or even dd
hdparm brings up the following (for both drives):
/dev/hdb:
HDIO_GET_MULTCOUNT failed: Invalid argument
I/O support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
HDIO_GET_NOWERR failed: Invalid argument
readonly = 1 (on)
readahead = 8 (on)
HDIO_GETGEO failed: Invalid argument
busstate = 1 (on)
HDIO_GET_ACOUSTIC failed: Invalid argument
Its the HDIO_GET_ACOUSTIC that puzzles me, as both drives rip audio
perfectly under win98, but fill up my dmesg with "lost interrupt" under
Linux.
This problem has been recurring with VIA chipsets throughout the 2.4.x
series and searching the kernel listr archives shows a few other people
having the same lost interrupt problem but not getting it resolved.
This is driving me crazy... can anyone suggest a fix or is there any
information you need to assess why this is happening?
Many thanks,
mikeH
