Re: kernel BUG at slab.c:804!
I'd guess this is because of a bug that crept into test9, where a TD is now leaked ... you can get rid of the slab BUG warning by commenting out the line at the top of drivers/usb/usb-ohci.c that #defines OHCI_MEM_SLAB. That TD leak prevents the kmem_cache from getting freed, and hence prevents that module from getting reloaded. It was a mistake to leave that #defined at this time, though of course it _ought_ to be fine to do that. - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
