Boot problems with pata_via driver

Boot problems with pata_via driver

[Patrick Ale]

Hi,

With kernel 2.6.19 I was able to boot using the pata_via driver
I tried to compile 2.6.20-rc6 and now I get a "unknown device: sda3"
error when I try to boot.

I compiled 2.6.20-rc6 by copying over the .config from the 2.6.19 tree
and running a make oldconfig && make

Am I doing something wrong?

Both kernels are self-compiled or is 2.6.19 a distribution kernel?

It could be that 2.6.20-rc6 has a bug and therefore no longer is able to 
use your controller.
It's also possible that the enumeration changed (e.g. sda is now an 
external hard disk).

During boot, there should be some messages prefixed with ata: and sda: 
describing what your kernel found and how it enumerated them.
What do they print with 2.6.20-rc6?

  Morning!
  The 2.6.19 was self-compiled, using the gentoo-sources-rc4 AND using
  the vanilla 2.6.19 from kernel.org (I was recommended to use vanilla
  sources with my ATI drivers), both worked.

  2.6.20 is self compiled to. I will give you the kernel output when I
  am at home, I will have to connect a serial cable to my laptop and use
  the scrollbuffer since on a kernel panic or system crash my keyboard
  leds start to blink, which the kernel sees as a device addressing
  hardware directly and giving me a kernel message for every blink :D

  Oh, and pata_via is the ONLY driver I have compiled built-in,
  regarding libsata. As I mentioned in previous mails I have quite some
  controllers and disks, but pata_via (my onboard IDE) has only two
 drives attaches, on IDE0 (in 2.6.19 ata0) my boot disk

  I also tried to boot with scsi_mod.scan=sync, this didnt work either

  More info follows, thanks for your time allready :)

Okay so, I unplugged the keyboard the moment I selected a kernel to boot.
The last thing i see on my screen, regarding SCSI is:

scsi 0:0:0:0: Direct-Access       ATA      WDC WD2000JB-00G 08.0 PQ: 0 ANSI: 5
scsi 1:0:0:0 CD-ROM               AOPEN DUW1608/ARR         A060 PW: 0 ANSI: 5


then later on:

VFS: Cannot open root device "sda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Funny, when I look at my dmesg log when I boot the 2.6.19 kernel (which works)
then I seem to miss something in the kernel output when I boot the
2.6.20 kernel.

When I boot 2.6.19 I see:
scsi 0:0:0:0: Direct-Access     ATA      WDC WD2000JB-00G 08.0 PQ: 0 ANSI: 5

SCSI device sda: 390721968 512-byte hdwr sectors (200050 MB)
sda: Write Protect is off

SCSI device sda: drive cache: write back
 sda: sda1 sda2 sda3 sda4 < sda5 sda6 >
sd 0:0:0:0: Attached scsi disk sda
sd 0:0:0:0: Attached scsi generic sg0 type 0

Does 2.6.20 see my IDE bus but it doesnt probe for drives?

*sigh* sorry for wasting your time, I found my problem.
Since I thought libata worked like my old ata drivers and 2.6.19 was
booting well, I reconfigured my kernel source and changed
CONFIG_BLK_DEV=y to CONFIG_BLK_DEV=m, since I genuinely thought I
wouldnt need additional disk drivers since I never needed them for
IDE. I compiled the kernel and all but never copied over the bzImage
over to /boot/

Now, I grabbed the config from 2.6.19 , copied it to 2.6.20, ran a
make oldconfig && make && make_modules and copied the bzImage to
/boot/. Of course, the 2.6.20 image I try to boot DOES contain the
CONFIG_BLK_DEV=m , so it wont find any disks, since the module is not
active (I dont use ramdisks).

I reconfigured 2.6.20 with CONFIG_BLK_DEV=y , and its working now.
idiot I am, what else can I say.

Again, sorry for wasting your time.
