Hi,
While migrating from kernel 3.8 to kernel 3.9 I've detected a problem on my
S3C2416 based board. I'm using UART 3 as console and with kernel 3.9 I'm
unable to have a getty working on that port and see a lot of these on
dmesg:
samsung-uart s3c2440-uart.3: cannot get irq 94
Also WDT is not correctly initialized in 3.8, I see in dmesg:
s3c2410-wdt s3c2410-wdt: watchdog inactive, reset disabled, irq disabled
while in 3.9 I see:
s3c2410-wdt s3c2410-wdt: tmr_margin value out of range, default 15 used
s3c2410-wdt s3c2410-wdt: failed to install irq (-38)
s3c2410-wdt: probe of s3c2410-wdt failed with error -38
So I guess something is broken in 3.9 kernel's IRQ handling for S3C2416.
when I checked two days ago, the irqs where working fine on my s3c2416 board.
Basic questions, did you change the init_irq callback to the correct new
function (s3c2416_init_irq) in your board file, can you provide a more
complete log and of course and is your board-file available somewhere?
My bad! I missed that change on the init_irq callback. Everything is working fine now.
Thank you and sorry for the inconvenience.
Best regards,
José Gonçalves
