2006-06-17[PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger
A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

2006-06-17[PATCH] fix cdrom openJens Axboe
Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

2006-06-13[PATCH] sky2: stop/start hardware idle timer on suspend/resumeStephen Hemminger

2006-06-12[sky2] Fix sky2 network driver suspend/resumeLinus Torvalds
This fixes two independent problems: it would not save the PCI state on suspend (and thus try to resume a nonexistent state on resume), and while shut off, if an interrupt happened on the same shared irq, the irq handler would react very badly to the interrupt status being an invalid all-ones state.

2006-06-11[PATCH] Fix for the PPTP hangs that have been reportedPaul Mackerras
People have been reporting that PPP connections over ptys, such as used with PPTP, will hang randomly when transferring large amounts of data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530. I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.

2006-06-11[PATCH] sata_mv: grab host lock inside eng_timeoutMark Lord
Bug fix: mv_eng_timeout() calls mv_err_intr() without first grabbing the host lock, which can lead to all sorts of interesting scenarios. This whole error-handling portion of sata_mv is nasty (and will get fixed for the new EH stuff), but for now this patch will help keep it on life-support.

2006-06-11[PATCH] PCI: reverse pci config space restore orderYu, Luming
According to Intel ICH spec, there are several rules that Base Address should be programmed before IOSE (PCICMD register ) enabled. For example ICH7: 12.1.3 SATA : the base address register for the bus master register should be programmed before this bit is set. 11.1.3: PCICMD (USB): The base address register for USB should be programmed before this bit is set. .... To make sure kernel code follow this rule , and prevent unnecessary confusion. I proposal this patch.

2006-06-11[PATCH] PCI: Error handling on PCI device resumeJean Delvare
We currently don't handle errors properly when resuming a PCI device: * In pci_default_resume() we capture the error code returned by pci_enable_device() but don't pass it up to the caller. Introduced by commit 95a629657dbe28e44a312c47815b3dc3f1ce0970 * In pci_resume_device(), the errors possibly returned by the driver's .resume method or by the generic pci_default_resume() function are ignored.

If that is off we will get timeouts. 2) Always try to sync with the firmware, if there is no firmware running do not treat it as an error and instead just report it the first time we notice this condition. 3) If there is no valid SRAM signature, assume the device is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT.
