What do you mean by not being able to enable > write-caching? Had a major crash (had to push the switch off) and now things behave very different! Now when I say hdparm -W1 /dev/sdb and then check, the write cache is finally on! Also, the booting went without a hitch see log at the end. > SRST failure puts the host port into non-responding state and the driver > resets the host port which in turn resets the PMP, so libata tries to > reinitialize everything. Can you post boot log with printk timestamp > (CONFIG_PRINTK_TIME) turned on? Will do if the hard/soft reset appears again, for the moment everything behaves differently from before (maybe because the card did not reset the array when I switched the laptop off?)
