The only way to start the laptop again was with Failsafe This is because acpi=off is passed and the acpi driver for the sony hid SNY6001 device is not loaded.

Another possibility is to put the Sony_laptop module on the Blacklist This should be your preferred workaround until it's fixed.

Hmm, it's a bit difficult to reproduce what exactly happened. I could try to find the exact kernel you used and try to find the command issued at: sony_pic_irq+0xfa/0x15a Do you remember a bit more about the error (should be at the beginning of the panic/oops), maybe a divison through zero, NULL pointer dereference, ... Maybe Mattia already knows about this one? If yes, I can point you to an already compiled 2.6.24-rcX kernel to try whether it's already fixed for you... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Puhh, this looks like a rather intrusive patch... On the other hand side, only the sony_laptop module is involved and if Mattia could tell me since when this is mainline or give me a risk estimation, I can add this to 10.3. Rudolf: You can try the latest 2.6.24-rcX kernel from here: ftp://ftp.suse.com/pub/projects/kernel/kotd/HEAD/ (You may need to update some -kmp packages or some may not work..., but it should be fine to test the sony_laptop capabilities). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=344132#c5 --- Comment #5 from Mattia Dongili 2007-11-27 17:08:22 MST --- Thomas, there are actually 2 patches, 1 to avoid the oops and 1 the make the driver work on those old vaios. The former has been included in 2.6.23 via the stable queue, the latter went in 2.6.24-rc1 exactly because it was a bit too intrusive. I'm not sure it's really worth backporting the big patch for a couple of reasons: - very few are bitten by this bug, this is the 4th report I receive since 2.6.22 - sonypi is still there and functional (without meye support though) I think it mainly depends on how long you'll have to stay with 2.6.22, if it's going to be a long time then backport it, if not just wait to ship 2.6.24. Of course I can help in backporting if this is your choice. ;) mattia -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Ok, I'd like to have the fix for the general kernel panic that went into 2.6.23.X...

heh, I bit of confusion on my side. The fix I was mentioning in the stable queue was for 2.6.22.2 and was this: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=commit... the patch you want to fix the oops in sony_pic_irq is

2007-08-24 Mattia Dongili sony-laptop: call sonypi_compat_init earlier

it went to Len some time around .23-rc4 and is not actually related to the kernel bugzilla entry I pointed out before. So 2.6.23 final should be ok as well for the OP. I first noticed this bug on my old vaio that has a jogdial (which the OP mentions) and is a GR model.

Something else: It looks like the resources (_CRS/_PRS/_SRS) are parsed by the sony laptop module itself? I expect this could be done easier using the pnp layer. Hmm, but I am not sure how this works if you have/want a pure acpi driver attached to your PNPxy HID, do you need to register a pnp driver then instead? Bjorn should know, hmm I won't CC him here, maybe this should be asked on ACPI list with Bjorn CC'ed for broader audience...

thanks for pointing this out, I'll take a look at the acpi pnp layer and see what I can work out eventually asking on linux-acpi. mattia -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
