He clearly isn't drunk, and you clearly are not as funny or clever as you think you are.

This kind of arrogance and unprovoked rudeness should not be tolerated by any open source project, you drag the project your working for down as much as you do people's opinions of yourself.

--- Comment #4 from Borislav Petkov <[email protected]> 2009-10-20 06:58:38 --- Hi,

does libata also fail to detect your drive? I.e., turn off CONFIG_IDE and enable CONFIG_PATA_VIA.

libata seems to find the drive fine -- abcde and mplayer are happy with it, vlc won't play it, but i suspect that's vlc's problem.

I play around a bit tonight to see if the change is fine -- my drives all have different names now...

Thanks.

You can always have stable device names with udev:

--- Comment #7 from andrea <[email protected]> 2010-01-11 13:49:29 --- I had a problem which sounds very similar last week.

I started a forum thread here (before I discovered this DB):
http://www.linuxquestions.org/questions/linux-virtualization-90/2.6.31-kernel-guest-os-on-vmware-esx-3.5.0-780042/

The solution (for us) was to regress out this kernel change:
http://kerneltrap.org/mailarchive/git-commits-head/2009/6/12/5948973

A more resilient fix might be to leave ide_probe_port() as-is but to fix ide_wait_not_busy() to return the last successful rc code (only returning -ENODEV if strictly no device is detected on the IDE port). I do not know what other repercussions such a fix might have however.

--- Comment #8 from Thomas Jarosch <[email protected]> 2010-03-03 12:07:18 --- Same issue here on vmware server 1.08: The IDE cdrom is not detected anymore on kernel 2.6.32.9. I've reapplied the patch to 2.6.32.9 and will attach it here for easier access.

PATCH 1/1 IDE Probe fails to find CD drive

In reply to a message not in the archive

http://bugzilla.kernel.org/show_bug.cgi?id=14438

--- Comment #11 from Thomas Jarosch <[email protected]> 2010-03-03 12:22:52 --- Thanks for the tip, Alan. The patch was meant as a hint or PoC, there must be a reason why the IDE controller is returning "no devices attached". Just added it for the IDE maintainer to get an idea what might be wrong.

I also can't sign the patch as I didn't write it in the first place, can I?

Reverting the commit mentioned above should do the same trick:
http://kerneltrap.org/mailarchive/git-commits-head/2009/6/12/5948973

btw: I guess it's a good idea to add the original author as CC:.
