I have following problem with EPP detection:
When loading paroport (with or without params) on my via KT-133 (686a) chipset,
EPP1.9/EPP1.7, EPP is not detected correctly with ECP/EPP enabled, due to
`Intel BUG check' in parport_EPP_supported().
In the first iteration of `Intel BUG check' (i=0), clear_epp_timeout(pb)
returns 1, because condition if (!(parport_pc_read_status(pb) & 0x01)) is true,
due to retval of parport_pc_read_status(pb), which is 0x78.
In the 2.2 kernels, EPP is detected correctly.
I have encountered similar problem (but without this debugging) on my old 486
with UMC chipset, where with 2.2 kernels EPP is detected, but with 2.4 not,
even with ECP disabled. I will do some debugging later.
If you know, what causes this behaviour (e.g. faulty chipset), pls let me know.
