[microblaze-uclinux] crash of PetaLinux RC3 (kernel 2.6)

["Brettschneider Falk" <fbrettschneider@xxxxxxxxxxxxxxx>]

Hi,
my user application which is heavily IRQ-driven kills Linux after a few minutes anywhere. The same one is rock-stable when using it with kernel-2.4.

I wanted to know where it crashed, so, in a first attempt, I did:
 xmd
 xload mhs system.mhs
 connect mb mdm
 rrd pc
and can see it's 0x80001f2c. Next I checked the file linux-2.6.x/System.map and it's within restore_context which is at 0x80001ebc. The offset is 28 bytes, so I suspect it crashed at "lwi r12, r1, PT_R12".
I do use the latest patches known from this thread http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2007/07/msg00027.html.

Do you have an idea what to do now?

Cheers, F@lk
