The old adaptec driver works on 22-2a, 22-2f, and 22-2g (built as a module, as long as you don't build the new driver at all and of course rename the object file), and Ben's latest kernel 2.4.22-ben1 from bk does not exhibit the problem with the new adaptec driver built as a module (It however blanks my screen (22" cinema on an ATI 7500) as soon as I try and start x - can't even switch consoles). All of the kernels except the benh one were built using the config file in the configs directory changing only the adaptec driver with menuconfig. The benh kernel was built with the config from 22-2f and an oldconfig done. cpuinfo is as follows: cpu : 7450, altivec supported clock : 733MHz revision : 2.0 (pvr 8000 0200) bogomips : 730.72 machine : PowerMac3,4 motherboard : PowerMac3,4 MacRISC2 MacRISC Power Macintosh board revision : 00000000 detected as : 69 (PowerMac G4 Silver) pmac flags : 00000000 L2 cache : 256K unified memory : 1536MB pmac-generation : NewWorld Card Spec's are: 10:12.0 SCSI storage controller: Adaptec AHA-7850 (rev 03) Subsystem: Adaptec AHA-2904/Integrated AIC-7850 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- I'm attempting to compile a stock 2.4.23 on my PowerMac G4/667, and > appear to be hitting the same bug that Ethan Weinstein reported a while > back.
