Hello,
I've got an older Acer C720 with r314251, which was not booted for some time,
and now panics on boot, also in single user mode, saying:
...
Dec 30 19:54:26 c720-r314251 kernel: ada0: Command Queueing enabled
Dec 30 19:54:26 c720-r314251 kernel: ada0: 244198MB (500118192 512 byte sectors)
Dec 30 19:54:26 c720-r314251 kernel: WARNING: WITNESS option enabled, expect reduced performance.
Dec 30 19:54:26 c720-r314251 kernel: Trying to mount root from ufs:/dev/ada0p2 [rw,noatime]...
panic: invalid bcd 194
...
The message comes from
$ find * -type f -exec fgrep "invalid bcd" {} /dev/null \;
sys/sys/libkern.h: ("invalid bcd %d", bcd));
$ vim sys/sys/libkern.h
...
#define LIBKERN_LEN_BCD2BIN 154
#define LIBKERN_LEN_BIN2BCD 100
#define LIBKERN_LEN_HEX2ASCII 36
static inline u_char
bcd2bin(int bcd)
{
KASSERT(bcd >= 0 && bcd < LIBKERN_LEN_BCD2BIN,
("invalid bcd %d", bcd));
return (bcd2bin_data[bcd]);
}
Any idea what could be damaged the system and what to do or check before
re-setup?
Thanks
matthias
