Description of problem:
the LiveCD boots the kernel okay but then it can't find the root file system
(which is, presumably, on the CD) - so i guess it can't find the CD drive.
Version-Release number of selected component (if applicable):
fedora 9 alpha LiveCD i386
there's plenty of noise about this in various forums. looks like maybe it used
to work around kernel 2.6.8. i saw a post saying that ubuntu warty worked.
Which actual hardware is this? And does the PCMCIA cd drive work in other cases
on an already installed system?
hardware is a toshiba portege P2000. (about 5 years old). the CD drive works
well enough to boot the kernel.
the drive works fine on a running fedora 8 on the same laptop model.
can i get more useful information from that running system? what would be the
most helpful stuff i can get?
with the drive plugged in on running f8:
lspci has the "ToPIC100 PCI to Cardbus Bridge with ZV Support", using driver
yenta_cardbus. lspci -n calls it 1179:0617 (rev 32)
pcmcia.prod_id1 = 'FREECOM'
pcmcia.prod_id2 = 'PCCARD-IDE'
pcmcia.prod_id3 = 'REV836'
which has a child scsi_host with a child:
info.linux.driver = 'sr'
scsi.model = 'CD-224E'
scsi.vendor = 'TEAC'
on insert the system log gets the following:
kernel: Driver 'sr' needs updating - please use bus_type methods
which appears on the screen just before the LiveCD fails.
lsmod contains sr_mod, cdrom and pata_pcmcia.
hope that's of some use. :-)
Added some bits so that the right modules should get pulled into the live initrd
and should be testable with F9 beta. Thanks!
w00t! here come's the beta :-) looks like all the modules are available,
thanks for that :-D, ... but the system doesn't know what to do with them, so
we get the same result.
here's what goes in /var/log/messages when i insert the pcmcia card with a CD in
the drive on fedora 8:

i'll try it again and see if i can mount manually from the command line.
booting from the fedora 9 beta live cd you get to the command prompt with no root.
removing and inserting the card elicits the "pccard: PCMCIA card inserted into
slot 1" (and matching 'ejected from') message.
so the first missing message is:
cs: memory probe 0xa0000000-0xa0ffffff: excluding 0xa0000000-0xa00fffff
maybe we need another module? or some hotplug magic? or something.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
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:
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.
