Block notifier/writer KDL'es while checkin out Webkit source code on a USB stick BFS formatted

[emitrax]

Backtrace attached.

Supposedly a USB problem. Please attach a syslog (be sure to continue and sync before rebooting).

Other than that, in a production release the block notifier/writer shouldn't panic(), of course.

Does reboot sync's automatically ?

I got other crash after reboot. I tried continuing with git checkout and git crashed itself, then after continuing, media checker KDL'ed on get_cache_blocked, but I don't know if all this is related so I'm not sure opening another bug is correct.

My worries is that all this crashes and KDL somehow corrupted the BFS partition on the stick, and they are causing all the other bugs. I'll run checkbfs if it's in the image.

BTW: this bug was on vmware one of the last revision (last checkout was yestarday 4th November).

No matter how corrupted the BFS image would be, it wouldn't cause these errors (only different ones ;-)).

Besides that, BFS is a journaled file system, and shouldn't corrupt due to KDLs.

Replying to axeld:

I also run the test and found not error (only a suggestion of three blocks that could be deleted, but how?)

Then new bug it is. :-)

It's not a suggestion, it's the simple past.

(In #4940) Obviously the same as #4901. The NULL pointer stuff is also obviously not true, or else the error would look differently.

Had a similar problem, also happened again while linking some part I can't remember.

Hopefully no typos in attachment (writing it all into notepad was painstaking!) :)
