Hi everybody!
An openSuse 11.2 system reliably refused to boot properly with kernel 2.6.38.8
although the prior 2.6.38.y kernels worked fine. After a few seconds booting
stopped. Several <ctrl-c> did help, but a lot of services were not started properly,
only the root partition was available. Nothing unusual could be found in the
kernel messages.
I bisected the problem to commit 5fb46ae7b8c51b05a12c6a66108e8d398c20ee09.
That gave me the idea to disconnect the Plextor PX-755A dvd drive and to
try 2.6.38.8 again. It booted without problem.
As I do use the dvd drive only once or twice a year on that system I checked the
hardware - it seems that the drive has a mechanical or optical problem.
No kernel can repair a broken dvd drive, but I strongly believe that at least
error handling should be restored to something more reasonable.
cu,
Knut

ide: Convert to bdops->check_events()
commit 5b03a1b140e13a28ff6be1526892a9dc538ddef6 upstream.
Convert ->media_changed() to the new ->check_events() method. The
conversion is mostly mechanical. The only notable change is that
cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT.
It used to return -EINVAL which would be treated as media changed. As
media changer isn't supported anyway, this doesn't make any
difference.
This makes ide emit the standard disk events and allows kernel event
polling. Currently, only MEDIA_CHANGE event is implemented. Adding
support for EJECT_REQUEST shouldn't be difficult; however, given that
ide driver is already deprecated, it probably is best to leave it
alone.

And I cannot duplicate this. My problems are shutdown/reboot related, it "turning off swap" "-f" on the next line, and it is hung till I tap the hardware reset button. In your case I'd suspect something in the Plextor that could be as simple as a dusty led/ir combo that detects the disk. But dvd writers have become so cheap they are hardly worth pulling the covers off to check. Cheers, gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

There's nothing I can do right now for the .38 series to resolve this, sorry. greg k-h ^ permalink raw reply [flat|nested] 5+ messages in thread
