USB disconnects on HP DL360 G7 server
-
Hi. I installed pfSense 2.4.4 onto a USB flash drive on an HP DL360 G7 server. I am experiencing intermittent USB disconnects causing the OS to crash and system to reboot. I tried changing the power save settings in the BIOS and going as far as disabling all the BIOS power save settings and I still get intermittent USB disconnects.
Just as a test measure, I installed VyOS (Debian Linux based) router OS onto the flash drive and set the BIOS power save settings back to default values. Over a twenty-four hour period it did not experience a single USB disconnect.
I repeated the above using a different brand flash drive and experienced the same results.
Any ideas what default kernel/driver parameters in pfSense that may be causing these USB disconnects and what parameter values should be used to rectify the problem? Any other possible issues that may be causing the problem?
In advance, thanks for any help you can offer.

What do you see logged? Or on the console?
Make sure you have 'Hard disk standby time' set to 'Always On' in System > Advanced > Misc.
Though I don't expect that to make any difference here.Steve

I tried using an SD card instead of a USB flash drive and that appears to have resolved the problem. I have no idea why that made a difference, though.

Probably some power saving feature that SD doesn't do.
