    ...
    e1000_clean_rx_irq_ps+0x3ca/0x470 [e1000e]
    
    Tzn. to vychcipne na spin lock pri vyprazdnovani RX fronty na sitovce.. 50c

    Vypadá to na bug v jádře (teoreticky by to mohl být i důsledek nějakého hardwarového problému). Jádro je distribuční a poměrně staré, informací je málo a podle toho, co píšete, je to jednorázový incident, takže jedině zkusit to reportovat v tom Debianu a doufat, že je to nějaký problém, na který už někdo narazil a buď už našel řešení nebo má aspoň víc informací.

    To bych netvrdil. Jednak je toho mezi těmi dvěma funkcemi dost dalšího (a s pár výjimkami to dává dobrý smysl), jednak kdyby to opravdu viselo na tom spinlocku, bude to tam ještě o těch 21 ms později, když se ozval RCU stall detector. Navíc je už u toho hard lockupu nastaven 'W' taint flag, takže je docela dobře možné, že tohle všechno už je jen důsledek něčeho, co se stalo předtím. Spíš bych tipoval nějaký problém buď v connection trackingu nebo timerech. Ale bez dumpu nebo aspoň kompletnějšího logu těžko říct víc.

    Podival bych se jestli neni dostupny novejsi firmware..

    No, zkusit to může, ale jelikož stack traces ukazují daleko spíš na conntrack, moc nadějí bych tomu nedával.

    Ideální by bylo zvětšit buffer (parametr log_buf_len na příkazové řádce) a nastavit kdump. Pak by se dal z dumpu vytáhnout celý log a v případě potřeby se i podívat, co se tam přesně stalo. Asi i nastavit sysctl kernel.panic_on_oops a kernel.softlockup_panic, aby byla větší šance, že se problém chytne co nejdřív.

    Hlavně ale bude potřeba někdo, kdo to bude ochoten analyzovat, takže s ohledem na to, že jde o distribuční jádro a navíc (z pohledu upstreamu) dost staré, bych doporučoval reportovat problém tam, kam patří, tj. v bugzille té distribuce.
