| |
I am trying to suspend-to-disk using the Suspend2 modules. I am using an SSD drive connected through a SAS bus interface. The SSD acts as a boot disk. All read and write transactions to the drive works well during normal operation. when I hibernate (suspend-to-disk).
I get the following errors: ------------------ mptbase: ioc0: ERROR – Invalid IOC facts reply, msgLength=0 offset=6 pnp: Failed to activate device 00:09. pnp: Failed to activate device 00:0a. ------------
Immediately after these messages, Linux hangs as soon as it starts writing the image to the drive. showing the following output. ------------------ Writing Kernel and process data ... 20%... ------------------
When using KDB to trace the problem after the kernel hung.
<ps> shows a running process: Ks2io
when doing Back Trace for Ks2io wheen the kernel hangs, I get the following trace -------------------- _spin_unlock_irq+0xb thread_return+0x64 _raw_spin_lock+ox90 __mutex_up_process+0x10 wake_up_process+0x10 suspend_bio_write_page mutex_lock+0x2a flush_workqueue+0x51 kblockd_flush+0x10 do_bio_wait+0x1b suspend_bio_write_page suepend_bio_write_page+0x41 suspend_compress_write_page+0x137 worker_rw_loop worker_rw_loop+0x133 worker_rw_loop kthread+0xf5 schedule_tail_0x45 child_rip+0x45 worker_thread kthread child_rip --------------------
It seems that the problem is when suspend2 tries to write to the SSD drive. I am not sure whether the problem is with the suspend2 module or the mpt driver? I am using kernel 2.6.21.1 x86_64 with fedora core 5 x86_64. MPT driver 3.04 Any insights/recommendations will be greatly appreciated.
