Hi everybody,
the problem I already reported for earlier release candidates of kernel 2.6.20
(rc1 – 5) unfortunately stills persists.

The regression has become more extreme: While in earlier release candidates nerolinux recognized my burning devices at least after the first start and then never again after all following starts the situation in rc6 is different from that:

The CD and DVD burning devices aren´t recognized even once and the drive seek errors I already reported are still there.

nerolinux runs excellently with kernel 2.6.19.2, but only shows an “image recorder” (i. e. no burning device at all) in kernel 2.6.20-rc6.

Still hope that this terrible bug will not be part of the final version of 2.6.20!

Regards

Uwe

P. S.: I already reported that 2.6.20-rc4-mm1 is not bootable at all.

FWIW, I just tried it with 2.6.20-rc6, and can confirm.  Once nero is
run, the kernel never gives up retrying whatever command failed, so I
get...

[ 4362.972995] hdd: status error: status=0x58 { DriveReady SeekComplete
DataRequest }
[ 4362.981475] ide: failed opcode was: unknown
[ 4362.986183] hdd: drive not ready for command

endlessly.

Do you have time to bisect it?

Unfortunately, I'm git impaired.  I am rummaging as we speak though.

Ok, I'm personally heading to bed, but it rally should be as simple as

 - get the git tree in the first place
 - do

	git bisect good v2.6.19
	git bisect bad v2.6.20-rc2
	.. it will pick a point for you to try ..
	.. compile, boot, test ..

	"git bisect {good|bad}" depending on results

 - until (found)

(Of course, you should check that -rc2 really is bad to make sure. I think 
that's what Uwe reported, though. And I don't think we've done anything 
after -rc2 that could impact this, so I don't doubt it).
