| |
Hello, everybody!
So far I have spoken to Jari Ruusu <jariruusu@users.sourceforge.net> who is maintaining loop-AES and to Matthew Dharm <mdharm-usb@one-eyed-alien.net> who seems to be maintaining usb-storage at the moment.
Jari Ruusu helped me by locating the whereabouts of the following bug by reading my syslogs with debugging output from usb-storage and by providing some kernel patches to isolate the error: I am using a harddisk attached via a cardbus usb 2.0 card. On it I have an encrypted partition which I access via loop-AES. I can easily reproduce a complete deadlock in the usb-storage system by mounting my encrypted partition or copying files to or from it (depends on configuration).
That's what Jari Ruusu wrote on Sun, 09 Nov 2003: > It was very similar memory allocation failure again: usb storage RAM alloc > waited for pages to be freed, and all freeable pages were waiting to be > written out to your usb device. Same thing, just different place.

I did without posting my kernel config and my syslog files with the usb-storage messages as according to the FAQ this would be overkill.
If anybody is willing to help me I would gratefully send her/him all my logs and my previous correspondence on this topic :)
Greetings from Berlin && excuses for my bad English,
