System freeze/lockup/crash - kernel 2.6.32-33-generic - "Safely remove" USB drive

[Carl Turney]

Hi,

Thanks for any help you can provide, and for fixing this ASAP.

System completely freezes (with numerous hard disk filesystem corruptions) only on kernel 2.6.32-33-generic, every time I right-click and "Safely remove" Seagate model 9SF2A4-500 external 1TB USB drive.

Don't think it happens to simple USB memory sticks, but not willing to further corrupt my system just to find out.

NOTE: Was running kernel 2.6.32-32-generic when I ran the "ubuntu-bug linux" that started =this= report. Do not have this problem with 32-32.

Get exactly the same behaviour on both my desktop and laptop Intel 32-bit systems. Both have Ubuntu 10.4.2 and the same two kernel versions.

I run System > Update Manager daily.

Have endured this for a couple weeks, expecting others more knowledgeable to report it, and a patch to the Kernel to be distributed.

Happy to answer further questions, but you will have to email me at

as I don't see any bug report ID # here, and not sure I can navigate back to the correct web page.

Thanks again,

Remember: The automated bug reporting system here tells you all about my kernel 2.6.32-32, which I last booted up in, and which does NOT have the problem. The problem lies in kernel 2.6.32-33.

Should I go through this whole process again, after booting into the buggy kernel?

Thanks, Carl
