You know there are weeks (or months!) when everything is just plain wrong... While still fighting with my laptop (See "Help track a memory leak in 2.6.0..14), now one of the semi-production machines started to freeze without any indication... No Oops. Nothing in the logs. No response to ping, all network is dead. Trying to log on the console dies at random (sometimes in the middle of the login name entry), but I can still Alt+SysRq+{S, U,S,B}. Sometimes no response to any keyboard press... It is a DIY P4 machine with Asus P5GDC-V-Deluxe (i915G,LGA775), 2GB RAM, SATA WD740GD disk (using libata). Running (now) 2.6.14.3 with sk98lin-8.23.1.3 patched in (the in-kernel one does not recognise the NIC) and mppe-mppc-1.3.patch (using the box to test VPNs). Softwarewise it is a Gentoo machine, runnig apache-2.0.54, subverison-1.2.3, bugzilla-2.20, mysql-5.0.16, pptpd-1.2.3, ppp-2.4.3 and latest openss{l,h}. No X, no sound, no WiFi, no USB, no NFSv4 (just 3): it is a headless server-type box (on a KVM). When it does die, and lately this happens 2-3 times per 24 hours, there is nothing hwatsoever to indicate the cause - just dead. A strange thing is that after the box is restarted with Alt+SysRq+{S, U,S,B}, most of the times it cannot find the SATA drive (BIOS cannot recognize it), so I need to turn off the power physically. About the NIC: There are a few posts on the net that Asus shipped some MBs with broken SPD, so they don't work with linux. Found some king of cryptic patch at Asus site (for another board) and it sayd to apply cleanly, but NIC is still not recognized by the in-kernel sk98lin at all (flash was done after problems began, but might have made them appear more frequently?). 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 Gigabit Ethernet Controller (rev 15) Subsystem: ASUSTeK Computer Inc. Marvell 88E8053 Gigabit Ethernet Controller (Asus) Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at cfffc000 (64-bit, non-prefetchable) [size=16K] I/O ports at d800 [size=256] Expansion ROM at cffc0000 [disabled] [size=128K] Capabilities: [48] Power Management version 2 Capabilities: [50] Vital Product Data Capabilities: [5c] Message Signalled Interrupts: 64bit+ Queue=0/1 Enable- Capabilities: [e0] Express Legacy Endpoint IRQ 0 Capabilities: [100] Advanced Error Reporting Got another NIC and will try it tomorrow. Now that I get a repetitive freeze, is there anything to debug the problem? I guess, the point when kernel is still responsive to keyboard, but I cannot login. It sounds really bad, but a put a cron job to restart the box every 4 hours until I move it's functions off to another one... and it used to run 30+ days... Any help is appreciated.
