Subject: 2.6.22-rc4-mm2: GPF during suspend to RAM on HPC nx6325

Hi,

gregkh-driver-sysfs-use-singly-linked-list-for-sysfs_dirent-tree.patch breaks
suspend to RAM on HPC nx6325 (x86_64).

With this patch applied I get a general protection fault in mutex_lock+0x15
(kernel/mutex.c:91), called by sysfs_hash_and_remove() (fs/sysfs/inode.c:298),
called by threshold_cpu_callback(), called from _cpu_down().

Without the patch, the suspend to RAM works (the resume doesn't - there is
another patch that prevents the video from being restored after the resume -
but I'll carry out the bisection tomorrow. ;-)]

Greetings,
Rafael
