[Bug 491288] Re: File corruption after copying files via samba from Karmic to Karmic

[Raptor 2101]

Since "smbfs (2:3.4.0-3ubuntu5)" i experience same problems. I've
mounted my homedirs via CIFS. All works fine (servernio to get KDE-apps
working). After this update i noticed some "extrem" file errors while
using Opera (HD-Cache enabled) and Firefox. Trying to download something
always causes a damaged file. Every large file (> 500kb) results in a
damaged file.

If i switch from servernio to directio. Firefox and Opera works fine,
now javaws, skype and some other apps craches cause of file corruption.

But copying files from or to some "normal" mounts works perfectly.

smb.conf
>>[homes]
>>   comment = Home Directories

>>   writeable = yes
>>   available = yes
>>   guest ok = no

>>   browsable = yes

>>   inherit permissions = yes
>>   hide dot files = yes

mounting via pam_mount
