USB stick not recognized when plugged before boot

[skfir]

If I insert a thumb drive before the systems is loaded, the drive is not recognized, I have to take it off and insert again. If I don't remove it and reboot the machine, drive is not recognized after rebooting as well. And after reading from the drive, when I unpluged it, the system fell into debug mode.

this is possibly related to #2344

What revision are you testing with? The alpha release or something more current?

[skfir]

Just the alfa release.

Please attach an uncompressed syslog.

One more problem: when attempted to delete a folder from a flash drive system crashed to KDL. Please look at img_0015

The new attaachment looks like a problem of the FAT driver.

Replying to skfir:

And by "not recognized" you mean not auto-mounted or not available to mount from the mount menu? From the syslog, the drive and the FAT filesystem on it are detected just fine.

If I don't remove it and reboot the machine, drive is not recognized after rebooting as well.

Again, what exactly do you mean by "not recognized"? Does it not show up in the mount menu?

And after reading from the drive, when I unpluged it, the system fell into debug mode.

If you unplug it without unmounting this is perfectly expected and indicates that you just lost and/or corrupted some data. From the screenshot it looks like a read-write mounted filesystem wasn't able to write back changes when it was unmounted because of the unplug provoked media change event.

The second screenshot is very hard to read, but doesn't look related. It indeed looks like a FAT problem where a block was modified where no modification was expected. Might be a race condition and might be related to the cluster != 0 assert.

I'm going to close this one. Without further feedback all seems perfectly fine as explained in comment 8 above. I can only guess that by "not recognized" actually "not automounted" was meant as the syslog indicates the device and filesystem were detected fine.
