Hi Jean-Christophe,
I'm using linux 3.4-rc2 and it seems I'm running in the same issue that
was described there: https://lkml.org/lkml/2011/8/8/355
I didn't have a deep look into it but when I try to use ts_calibrate or
ts_test, the network interface is freezing. As I'm using nfs to boot, I
can't do anything anymore...
Kernel message:
# ts_calibrate

Hi again,
More info, I get almost the same behavior while booting from nand.
ts_calibrate and ubiattach seem to trigger the issue.

Yes, it is fixed in the patch posted a few minutes before by
Jean-Christophe:
[PATCH 1/1] ARM: at91: fix at91sam9261ek dm9000 irq
We have included it in our AT91 "fixes" branch and will submit it soon
for inclusion in arm-soc.
https://github.com/at91linux/linux-at91/commits/at91-fixes
Thanks to Alexandre for having reported this and to Jean-Christophe for
having corrected it so quickly.
