| |
Today I realized that doing something like:
estel:/proc/ide/hda# echo "wcache:1" > settings or echo "using_dma:1" > settings
results in: proc_ide_write_settings(): parse error proc_ide_write_settings(): parse error
Searching in the list it seems it has been broken at least since July. (This is test5)
Is this a know bug?
.config attached.
