lost interrupt

Sorry if this is a repeat, I didn't see my last post come through...

I'm being plauged with "hdX: lost interrupt" messages and resultant system hangs in kernel 2.4.18 on a via 82XXXX chipset.

Who should I direct my questions to?

Thanks in advance,

MikeH

I may not be the right person to answer but I had same problem (same via, same kernel, same interrupt). It helped when I turned unmasking off, i.e. try:

hdparm -u0 /dev/hdX for every X in existing disks you have problems with.

Actually I did some dirty trick too, cause I have UDMA enabled by default and compiled in via specific settings in kernel config, while at the same time I set dma off during init, so I do:

hdparm -d0a0u0 /dev/ide/host0/bus0/target0/lun0/disc (or /dev/hda).

I think -u0 is sufficient but you may try the other command too. My current dirty tricks are overreaction to problems with UDMA few kernels (and years) ago so the second command is for paranoids.

Thanks, I tried that but to no avail :(

To expand on the problem :

I have a creative DVD 5x drive and some unbranded CD-RW drive. The problem occurs on both when I try to rip audio.

I know for a fact they both have the capability to rip audio nicely, I have seen them do it under a 2.2.X kernel, but now I'm running 2.4.18 (I need 2.4 for my nvidia card)

However, hdparm returns this (on both drives, no matter what slave/master dma/irq combo I use)...

HDIO_GET_MULTCOUNT failed: Invalid argument

I/O support  =  0 (default 16-bit)
unmaskirq    =  0 (off)
using_dma    =  0 (off)
keepsettings =  0 (off)
HDIO_GET_NOWERR failed: Invalid argument
readonly     =  1 (on)
readahead    =  0 (off)

HDIO_GETGEO failed: Invalid argument
busstate = 1 (on)
HDIO_GET_ACOUSTIC failed: Invalid argument

See the worrying "HDIO_GET_ACOUSTIC failed: Invalid argument" ?

I'm not sure who is maintaining that part of the kernel though.

Thanks for any help,

mikeH

unmasking is already off on my drive

I'm getting the same thing (very rarely) with a BX chipset and 2.4.16. What CPU are you using? What type of disk is the hdX?

Padraig.

Its an AMD Duron 1.2ghz, the hdX is either my creative DVD 5x or my cd-rw (unbranded)
