Has this been resolved in current kernels? I don't use linux-cifs any more since 2 years, instead I use MS NFS server on the server, which is much more reliable for me. But I have now tested this problem, and it is still there: Client: Debian lenny, 2.6.26, cifs 1.56 Server: Windows 2003 x64 SP2 Gigabit LAN # mount //server/scratch /mnt -o serverino,user=...,pass=... With this mount I still get decreasing performance while copying a large file (600MB) from client to server (i.e. write to the share). (I used Midnight Commander (mc) for copying, and its throughput measurement.) Apparently the file is cached locally first, and this cache is then swapped out, later swapped in, and then transferred, causing increasing delays while copying. No problem when adding directio. Disk activity for the non-directio case is very high on the client, compared to the directio case. NFS read 18 MB/s NFS write 15 MB/s CIFS directio read 14 MB/s CIFS directio write 14 MB/s CIFS non-directio read 17 MB/s CIFS non-directio write 9 MB/s * * begins with 19 MB/s and then constantly decreases to 9 MB/s for the whole transfer in average.

Bug#373593: seems to work since 2.6.17
Wake on lan seems to work again since 2.6.17, i.e. I successfully tested: linux-image-2.6.17-2-686_2.6.17-8_i386.deb Martin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Bug#373593: kernel: e1000 wake on lan (wol) does not work after 2.6.12
Package: kernel Severity: normal Hello, when upgrading from linux-image-2.6.12-1-686_2.6.12-10_i386.deb to any of - linux-image-2.6.14-2-686_2.6.14-7_i386.deb - linux-image-2.6.15-1-686_2.6.15-8_i386.deb - linux-image-2.6.16-2-686_2.6.16-14_i386.deb - vanilla 2.6.15 wake on lan (wol) doesn't work any more with my e1000 card (Intel PRO/1000 MT Desktop Adapter with the e1000 driver). After shutting down linux, the link led is off now (nic and switch), and wol is not possible. wol is possible and working fine after starting and shutting down Windows 2000, or Linux kernel 2.6.12, where link led stays on on both nic and switch. I found a similar issue here with the sk98lin driver: http://www.linuxquestions.org/questions/showthread.php?t=444793 but ethtool is working for me with e1000.
