Subject: [BUG] 2.6.19-rc3 autofs crash on my IA64 box
Date: Wed, 01 Nov 2006 16:02:00 +0800 [thread overview]
Message-ID: <45485478.8060909@intel.com> (raw)
hi,
2.6.19-rc3 kernel crashes on my IA64 box, it seems the problem
of autofs fs. I debug this problem, if autofs kernel does not
match daemon version, it will call autofs_catatonic_mode.
But at that time sbi->pipe is NULL.
void autofs_catatonic_mode(struct autofs_sb_info *sbi)
{
.........
fput(sbi->pipe); /* Close the pipe */
^^^^^^^^^^^^
sbi->pipe seems NULL;
autofs_hash_dputall(&sbi->dirhash); /* Remove all dentry pointers */
}
Starting automount: autofs: kernel does not match daemon version
Unable to handle kernel NULL pointer dereference (address 0000000000000028)
