Greetings,
I'm porting 2.6.29 to our ARM9 (Micrel KS8695) based box. For USB
connections VIA VT6212 controller is attached to the PCI bus. If
connecting a card reader I get following error message concerning no-IRQ:

after that the card is correctly detected and I can mount and browse my
CF card. But all interactions with the card reader are going very
slowly, as if interrupts were disabled.

There were no such problem with 2.6.24 kernel. Our box uses two kernels:
1.“BIOS” kernel: will be started from internal 4Mb flash
2.“Final” kernel on external medium (to run final OS like Debian etc.).
This kernel will be started via kexec
Our BIOS kernel is 2.6.24, if the final kernel is 2.6.29 then I
experience no problems. But if I update BIOS kernel to 2.6.29 I have the
above described behavior. It looks like the VT6212 chip is initialized
correctly via 2.6.24 kernel.
Any idea what could be wrong?
Thank you in advance.
Best regards,
Yegor
