[BUG?] "bad: scheduling while atomic!" after modprobe -r aic7xxx
From: Kalin KOZHUHAROV
Date: Thu Jun 17 2004 - 12:33:14 EST
I was testing 2.6.7, now with LOCAL_APIC and it seems to be working (though my SATA disk is not connected).
However when trying to remove aic7xxx a lot of badness is outputed. Trying to isolate the problem I tested without the APIC (in BIOS and kernel) but the results were the same.
I am running on ASUS A7N8X-Deluxe (v2.0) MB with Nforce2 chipset.
Apart from the badness, no crash or freeze is happening.
I can reproduce it as many times as I try (=everytime).
Attaching the relevant debug output below, the two sets of files *_after.log and *_after_modprobe-r.log are taken after i loaded and unloaded the aic7xxx module.
