Bug 447050

sorry, device ID is ISAPNP\TBA03B0\FFFFFFFF

MP

well, blame the kernel if modalias-module-autoloading does not work with isa-pnp.

There's an entry in sb16.c for...

        /* Sound Blaster 16 (Virtual PC 2004) */
        { .id = "tBA03b0", .devs = { {.id="PNPb003" } } },

I wonder if it's a case insensitive match, and maybe Microsoft changed the case
for some reason in later versions of virtual PC.

Jaroslav?

Hello,
Sorry, I overlooked this important error messages on FC9 boot screen:

Decompressing Linux... done.
Booting the kernel.
PCI: 0000:OO:Oc.O: class 401 doesn't match header type 01. Ignoring class. 
isapnp: checksum for device 1 is not valid (0x89)
isapnp: checksum for device 2 is not valid (Oxbe)
Red Hat nash version 6.0.52 starting

Is there a workaround/kernel parameter to ignore these? Meanwhile I 
do "modprobe snd-sb16" in rc.local.

MP

The checksum lines are just warnings.

Could you attach dmesg after boot? (without added modprobe snd-sb16)?

Created attachment 309758 [details]
dmesg 

attaching dmesg as requested

MP

It really looks like case match problem. Could you verify what ID is in
/sys/devices/pnp*/*/id files for the audio device? If it's tBA03b0 or TBA03b0.

#cat /sys/devices/pnp1/01:01/card_id
tBA03b0

MP

It does not look like a kernel problem. Assigning to udev maintainer. I wonder
where you get the ISAPNP\TBA03B0\FFFFFFFF - converting everything to upper case
might fail in this special case.

/etc/udev/rules.d/80-drivers.rules:

SUBSYSTEM=="pnp", DRIVER!="?*", ENV{MODALIAS}!="?*", \
  RUN{ignore_error}+="/bin/sh -c '/sbin/modprobe -a $$(while read id; do echo
pnp:d$$id; done < /sys$devpath/id)'"

what is in /sys/devices/pnp1/01:01/id  ??

1. sorry for confusing you with uppercase - it must have been obtained from 
windows device manager instead of fc9

2. in /sys/devices/pnp1/01:01/card_id there's "tBA03b0" (no quotes). There's 
no "/sys/devices/pnp1/01:01/id".

3. not sure what should I do with 80-driver-rules. Should I post mine (it's 
dated may 6 and untouched by me)

Thanks!

MP

strange..

# find /sys/devices/pnp* -name id

Jaroslav: why card_id and not id??

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
