Subject: [2.5.75] Slab corruption
Date: Mon, 14 Jul 2003 20:03:37 +0200 [thread overview]
Message-ID: <20030714180337.GA918@dreamland.darkstar.lan> (raw)
Hi,
I got a slab corruption under 2.5.75. I was browsing with mozilla 1.4
and this was the only network load. Kernel is UP with CONFIG_PREEMPT.
Full .config is here: web.tiscali.it/kronoz/config-2.5.75
This is the first error:
Slab corruption: start=ef1962f4, expend=ef196af3, problemat=ef196503
Last user: [kfree_skbmem+20/48](kfree_skbmem+0x14/0x30)

It seems e100 fault... after that I saw other (maybe related) slab
corruptions. Full log is here: web.tiscali.it/kronoz/slab-2.5.75.txt
The CPU is quite cool and the system survived memtest some time ago.
