Hello,

known problem, patch sent to alan some time ago(may be i should
resync/resend?) for this dma_timer_expiry have several problems:
calls DRIVER(drive)->error - the one above, it's called with lock from ide_timer_expiry
calls ide_dma_end - the reason for called while not waiting messages, it's called again in ide_timer_expiry

there is one more locking problem known to me - HDIO_DRIVE_RESET, but can not find out how to fix it properly.

have fun,
alex

+++ calls handler under the lock, thats fixed in -ac, and thats above, not error.

have fun,
alex

Hi Alex!

Please resync with 2.5, put some nice comment and resend :-).

This was fixed in the 2.4-ac tree. I guess the 2.5 stuff hasn't picked up the changes yet
