8250 should have claimed ttyS3 in 2.6.21 and earlier. So from the 8250 point of view, 2.6.21 and 2.6.23 should behave the same. >From the smsc-ircc2 point of view, 2.6.21 and 2.6.23 should work the same except for the additional quirk_smc_enable(). If 2.6.23 is worse than 2.6.21, please try removing the body of quirk_smc_enable() and see whether that makes 2.6.23 as good as 2.6.21. For smsc-ircc2, 2.6.23 is definitely a regression from 2.6.22, because 8250 stayed out of the way in 2.6.22. But we had to revert 8250 back to the 2.6.21 behavior because the change swapped ttyS0 and ttyS1 on some machines, so we just have to live with that 8250/smsc-ircc2 conflict for the time being.
