This limits the rate of messages. Can you try if a this patch fixes behavior?
Yes, this patch fixed the problem and watchdog doesn't reset again.
Next is the console log when usb storage disconnected:
[...]
cp: read error: Input/output error
# [ 218.253995] FAT-fs (sda1): FAT read failed (blocknr 1130)
'FAT read failed' error message printed only once.
Interesting.
Hm, message should print 10 times, then is suppressed. So this time, the
test may not reproduced. Can your test reproduces the issue reliably?
Right.
I found copy file from usb storage to tmpfs or ubifs has the different
behaviors. I got only one error message when copy to tmpfs and got 10 error
messages when copy to ubifs. Next is the log when copy to ubifs:

My gpio watchdog toggle every 100ms and I sniffer watchdog toggle signal and
uart console, watchdog toggle time is 119ms when those message printed, delayed
19ms.
This patch can really solve this problem, thanks.
Well, anyway, the patch looks like working.
Thanks.
