Description
hrev30944; ata-bm; acpi;
Running random_file_actions without block cache (-n), I get a reproduceable error:
random_file_actions -m256000 -f20 -d10 -r2000 -vna

Running the same command without disabling the block cache,
random_file_actions -m256000 -f20 -d10 -r2000 -va
the runs complete successfully.
Repeating this in a tic-toc manner, always yields the same. W/o block cache, failure, with block cache, ok.
PS: Just tested on a second partition and it yielded the same result as above. Then wen't on to test on my main dev partition and got the following which looks a bit different:
153 replace "./random_file_temp/file-56" contents
write 203303 bytes

Took a while to hunt it down, but it's fixed in hrev30960.

Oh, that sounds perfect! I'll look into it.
