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

[Felix Bünemann]

I'm also getting this bug on Lucid. For me it crashed during copy of
large file over gige to afp share. System is an nvidia ion based
mediacenter with ext4 and lvm mdraid5 on 4x onboard sata drives.

Here's the backtrace:
