lost interrupt

[mikeH]

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

My so called competence ends here...

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.

Re: lost interrupt

[Mike]

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

lost interrupt

[Trevor Woerner]

I'm getting the dreaded "lost interrupt" whenever the kernel tries to
access my onboard CF card. I put an 'IDE_DEBUG' at the start of
'ide_intr()' so I could watch to see if/how many times my interrupt
occurs or gets called. As an example, after I run 'cardmgr' I'll get
7 'lost interrupt' messages. After the last one, I'll get 7
'IDE_DEBUG' messages indicating that there were 7 interrupts queued
and waiting on the correct interrupt line.

So if 7 interrupts are sitting there waiting on the correct line, why
can't they get into the kernel so it can know the CF card is ready,
instead of having to wait for each IDE operation to timeout? From
googling around the usual cause of 'lost interrupt' is setting the irq
incorrectly, but the fact that all 7 get delivered (eventually) to the
ide's 'ide_intr()' would seem to indicate that at least that part is
configured correctly, no?

[relevant info]
kernel: 2.4.20-rc1
interrupt: external #6 (known as 31 internally), shared
cpu: PPC405gp

in 'ide-cs.c' i call 'ide_setup_ports()' to configure the device and I
define an 'ack_intr()' in order to acknowledge and turn off the
shared interrupt. The interrupt is shared, but not with other IDE
hwif's. I'm not using DMA, chipset is 'ide_generic'. This is not a
PCI device.

How do 'ide_ack_intr()' and 'hwif->intrproc()' differ? I've only setup
'ide_ack_intr()', it appears to return a 1 if it determines the
shared interrupt source was the IDE, or 0 if it wasn't. I also use
this place to put the code to reset (or turn off) the interrupt. What
would 'intrproc()' do?

It gets a bit stranger, but I think I'm onto something. I'll try to
confirm this in the next day or so, but it appears on the surface that
my device doesn't give an interrupt between the transfer of each
segment in a multi-segment transaction.

I enabled the debug statements in 'ide-disk.c' and what I found is that
sometimes I receive interrupts and Linux is happy, and other times I
don't. After thinking about it a little bit I believe the times I got
interrupts were when single segments at a time were being read (ATA
command 0x20) and when I didn't get interrupts were when multi-segment
reads (still command 0x20 but with number of sectors > 1) were
performed.

Lost Interrupt

I compile 2.4.18 kernel with promise raid support, and when kernel is
checking my partitions say: Lost interrupt

any idea.

  Try Alan's ac kernel for the promise controllers.  It seems to work
for most people.

PS- You will need to patch 2.4.19-rc1 1st.

Lost Interrupt

[SoloCDM]

The present system has operated without any changes to the hardware
with Win9.x, RH5.2, and LM7.0.  This problem only started when I
upgraded to LM8.0 and still no hardware changes have been made.

I use the 420Mb drive as a swap disk, connected along with the
CD-ROM to the secondary port.  I can't bring myself to throw the
420Mb drive out.

The following errors occur during boot-up:
