[Bug 592589] Re: ext4 kernel bug (2.6.32-22) while writing on USB device

Sun Jun 13 19:36:17 UTC 2010

I had the same problem, and it completely locked up the system.

Disk stack:  ext4 on LVM on MDraid on SATA drives.
Operation:  Copying large (~700MB) files over network (GigE) and Samba.

System: Linux thresher 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3
22:02:19 UTC 2010 i686 GNU/Linux
