Titolo: [LUNGO] Unable to handle kernel paging e Bad slab magic

Da un po' di tempo (pero' ultimamente ho avuto un uptime di 28
giorni...) sperimento alcuni problemi con la mia Linux box.
Mi becco in kernel.log sfilze di

Linux Slackware 7.1 aggiornata a current per quanto riguarda libc e
compilatori (piu' perl e qualcosa d'altro), XFree 4.0.2 compilato dai
tarball, ho proviato sia con sia senza i driver originali Matrox (e
l'accelerazione AGP a 4x). Kernel 2.2.19 + patch ide di Hedrick (tra
l'altro ho appena visto che e' uscita una patch nuova per quel kernel,
provvedero' a installarla subito per l'intanto).
Idee? Suggerimenti?

Non e' che ti per qualche motivo ti finisce ram e swap ed il poveraccio
schianta?
Oppure potrebbe essere un banco di memoria bacato?

 Oppure potrebbe essere un banco di memoria bacato?
Un paio di settimane fa mi sono beccato un po' di Signal 11 mentre
compilavo alcuni sorgenti di vario genere al primo tentativo,(al secondo
invece la compilazione andava a buon fine)... argh... non voglio
pensarci... ieri cmq ho ricompilato il kernel senza particolari
problemi... boh?
La macchina (AMD K7 550) non e' overcloccata e ha una ventola
supplementare.
Cmq faro' dei test sulla ram...

 Cmq faro' dei test sulla ram...
Penso sia utile!

Capisco... intanto mi sono scaricato memtest86, lunedi mattina devo
spegnere la macchina per installare un nuovo hard disk (40 gb) e una
seconda scheda di rete per l'adsl, ne approfittero' in quell'occasione
per il test.
Tnx!

Ho testato la ram con memtest86... nessun errore... boh?
Intanto ne ho approfittato per agigungere 40gb di disco e una nuova
scheda di rete per l'adsl (che arrivera' a breve) :-)
