* [PATCH] libata: fix oops caused rescanning NULL sdevTejun Heo2006-06-121-8/+9
| | | | | | | | | | | | | Depending on timing, ata_scsi_dev_rescan() might encounter a device which is enabled but not yet attached to sdev. On such cases, the original code caused oops. This patch makes ata_scsi_dev_rescan() rescan only device which are attached to sdevs. While at it, properly indent leading comment and add description about how it's synchronized with sdev attach/detach.

* [PATCH] sata_sil: update device hotplug handling, take #2Tejun Heo2006-06-121-1/+19
| | | | | | | | | | | | | | | | | | SIEN on some 3112 controllers doesn't mask SATA IRQ properly. IRQ stays asserted even after SIEN is masked and IRQ is acked. Also, even while frozen, any SATA PHY event including hardreset raises SATA IRQ. Clearing SError seems to be the only way to deassert SATA IRQ. This patch makes sil_host_intr() clear SError on SATA IRQs and ignore SATA IRQs reported while frozen so that hardreset doesn't trigger hotplug event (which ends up hardresetting again). In such cases, the port still gets re-frozen to minimize the danger of screaming interrupts. This results in one nil EH repeat on controllers with broken SIEN but other than that does no harm.

| | | | | | | | | | | | | | | | | | | | | | Bug fix: mv_eng_timeout() calls mv_err_intr() without first grabbing the host lock, which can lead to all sorts of interesting scenarios.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ppa cannot handle highmem pages, and like imm, which already has this patch, the device is slow, so performance is not a big issue, so just force pages to be in low memory (hence mapped).

| | * | [SCSI] mptspi: reset handler shouldn't be called for other bus protocolsJames Bottomley2006-05-191-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All registered reset callback handlers are called during reset processing. The mptspi modules has its own reset callback handler, just recently added for issuing domain validation after host reset. If either the mptsas or mptfc driver are loaded, this callback could be called. Thus resulting in domain validation being issued for sas or fibre end devices. Fix this by having mptbase.c check the bus type against the driver type and only call the reset handler if they match (or if it's a non-bus specific reset handler).

I've talked to Willy about the problem, and he asked me to try to blacklist the device for reportlun. I did that with the patch below and it solved the problem.

| * | | [PATCH] md: Fix badness in sysfs_notify caused by md_new_eventNeilBrown2006-05-311-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: NeilBrown <neilb@suse.de> If an error is reported by a drive in a RAID array (which is done via bi_end_io - in interrupt context), we call md_error and md_new_event which calls sysfs_notify. However sysfs_notify grabs a mutex and so cannot be called in interrupt context. This patch just creates a variant of md_new_event which avoids the sysfs call, and uses that. A better fix for later is to arrange for the event to be called from user-context. Note: avoiding the sysfs call isn't a problem as an error will not, by itself, modify the sync_action attribute. (We do still need to wake_up(&md_event_waiters) as an error by itself will modify /proc/mdstat).
