Hi, I've just booted the 5.2.1-RC2 i386 kern + mfsroot floppies. After the kernel has booted and counted its devices, I can no longer enter data. The keyboard still works in the loader autoboot countdown but stops working when the kernel boots. Ctrl Alt Del are non-functional, only the reset button works. The pertinent keyboard is always a German 105-key QWERTZ Fujitsu Siemens Computers KBPC S2 with PS/2 connector. I have seen this with two different keyboards of this same FSC KBPC S2 type on three different mainboards, Serverworks (Xeon) and VIA chipset (AMD Duron/Athlon XP) based. This problem wasn't present in 5.1-RELEASE, I've seen it for the first time in November 2003 when I updated a FSC Primergy RX300 (single Xeon, HTT) test machine from 5.1-REL to 5-CURRENT. Other keyboards such as the older SNI-OEM TAPC-S or a Cherry G81-3000 are fine. I know three workarounds at this time (it seems the keyboard is slow to reset): 1. suppress detaching the atkbd driver after reset failure: hint.atkbd.0.flags="0" 2. suppress the keyboard reset: hint.atkbd.0.flags="3" 3. recompile the kernel with this options added: options KBD_RESETDELAY=1600 options KBD_MAXWAIT=3 I tried 3000, 2300 and 1600 for KBD_RESETDELAY all worked. 200 doesn't work. I haven't yet figured if the resetdelay can be lowered further (900 would be a candidate for the next kernel compile :-) Please consider including any of these workarounds for the final 5.2.1 release. -- Matthias Andree Encrypt your mail: my GnuPG key ID is 0x052E7D95
