Package: linux-image-2.6.26-1-686 Version: 2.6.26-12 Severity: normal
Within four hours after a client system resumes from suspend to ram, access on the client to the NFS filesystem hangs, access to all other filesystems eventually hang once cache is filled, and a flood of packets is observed on the NFS server being emitted by the NFS client. Both the NFS server and NFS client are running linux-image-2.6.26-1-686 2.6.26-12, and are on the same network switch. The symptom is cleared by typing "/etc/init.d/nfs-kernel-server restart" on the NFS server system "dors". At that time, the client regains normal operation and the flood ceases. The client has in dmesg: [13969.896074] Restarting tasks ... done. [24837.320033] nfs: server dors not responding, still trying [25140.408048] nfs: server dors not responding, timed out [25140.408048] nfs: server dors not responding, timed out [25140.500429] nfs: server dors OK A tcpdump of the packet flood shows 23783 packets over a period of 1.37 seconds. The packets consist of TCP SYN from the client to the server, followed by a TCP RST from the server to the client. The same port numbers are reused in each packet; source port rxe, destination port 2049. The tcpdump is available if required for analysis, but the user data in the packets is confidential. The symptom does not occur unless the NFS client system is first suspended or hibernated, using pm-suspend and pm-hibernate, and then resumed. Possibly unrelated observation; the disk access LED of the system is normally off unless the disk is being accessed, but after resume from suspend or hibernate the LED stays on. The disk can still be accessed. -- Package-specific info: ** Version: Linux version 2.6.26-1-686 (Debian 2.6.26-12) (wa...@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-24)) #1 SMP Mon Dec 15 18:15:07 UTC 2008 ** Command line: root=UUID=ce95ab50-301b-418b-8546-07b4d6cdd419 ro quiet splash resume=/dev/hda2 ** Not tainted ** Kernel log: [ 5.516369] ACPI: PCI Interrupt 0000:02:08.0[A] -> GSI 20 (level, low) -> IRQ 20 [ 5.607348] e100: eth0: e100_probe: addr 0xfe200000, irq 20, MAC addr 00:08:02:1b:d4:99 [ 5.664866] hda: max request size: 128KiB [ 5.668676] hda: 80063424 sectors (40992 MB) w/2048KiB Cache, CHS=65535/16/63 [ 5.668688] hda: cache flushes not supported [ 5.668787] hda: hda1 hda2 [ 5.691559] hdc: ATAPI 48X DVD-ROM CD-R/RW drive, 2048kB Cache [ 5.691574] Uniform CD-ROM driver Revision: 3.20 [ 6.007825] PM: Starting manual resume from disk [ 6.078592] kjournald starting.
